Five machines, five differently shaped slots, one coin. That is the whole problem: each tool takes a different unit of payment, so the same coin does not fit all of them.

Five WordPress image tools charge in five different units. Optimole counts visitors. ShortPixel counts credits. Imagify measures megabytes of images. EWWW meters bandwidth. Smush charges by site.

A cheapest-to-most-expensive ranking would compare unlike quantities. The useful question is simpler: which limit will your site reach first?

The short answer

Huge library, quiet traffic
Optimole: the visit ceiling is the one you will never reach
Heavy traffic, few images
Imagify or EWWW in local mode — paying per visit is the worst possible fit here
Both are growing and you want to stop thinking about it
NimboCDN: the only one with no traffic meter
A fixed roster of client sites
Smush: the only bill you can predict a year ahead
You want AVIF without paying
Imagify, with AVIF even on the free plan

What each one actually charges for

All of them shrink images. What changes is what they count while they do it, and that column weighs far more on your bill than the big number in the shop window.

Read the middle column with your own site in mind. A magazine with 4,000 archived photos and 3,000 readers a month blows through Imagify’s megabyte cap without breaking a sweat, and never gets anywhere near Optimole’s visit ceiling. A landing page with nine images and 200,000 visitors is the exact opposite. Same two products, opposite verdicts. Which one suits you does not depend on the tool: it depends on what your site is made of.

What an image CDN is — and why it takes weight off your server

An image CDN is a network of servers spread around the world that optimizes and delivers your site’s images in place of your server. Each visitor gets the image from a point on the network, already converted and sized for their screen — and your server drops out of that equation.

The practical effect is a division of labor. Images are usually most of a page’s bytes — we weighed how many, on 41 storefronts across 14 ecommerce platforms — and without a CDN it is your hosting that ships file after file to every visitor — when its job is to run the site. With delivery delegated, your server is free for what actually matters: the catalog, the cart, the content. That is the difference between the two families in the table above: a compressor makes files lighter where they sit; a CDN optimizes and takes delivery off your server’s back.

Why the units do not convert

It helps to picture a chain. Someone arrives, loads a page, the page asks for images, the images travel as bytes. Each tool taps a different link:

Where each tool puts its meter, from visitor to bytes deliveredA visitor enters on the left and a delivered image leaves on the right, through four stages. Optimole meters stage 1, Imagify and ShortPixel meter stage 3, ShortPixel and EWWW also meter stage 4, Smush charges per site before the chain and NimboCDN meters nothing.IN · a visitorOUT · an image1Visitorunique daily user2Page viewrequests images3Imagesprocessed4BytesdeliveredOptimoleImagifyShortPixelShortPixelEWWWSmushcharges per site,before any of thisNimboCDNno meteranywhere Where each tool puts its meter, from visitor to bytes deliveredA visitor enters on the left and a delivered image leaves on the right, through four stages.

Where each tool taps the chain. Optimole counts the visitor arriving; Imagify and ShortPixel count the images they process; ShortPixel and EWWW also count the bytes going out. The two on the bottom row sit outside the chain: Smush charges per site before any of it, and NimboCDN measures at no point at all.

Five meters in five places. That is why a “normalised” price table would have to invent how many images a page carries, how many bytes each one weighs and how many pages a visitor opens. No vendor backs those assumptions, and an invented assumption is not a comparison: it is a hunch with table borders.

Why people look for Optimole alternatives

Optimole has more than 200,000 active installations and a 4.7 rating on WordPress.org. This comparison does not measure product quality. It examines the billing model, where three limits tend to matter.

  1. The ceiling arrived before the payoff. Paid plans start at 48,000 visits a month. Cross that and you move up a tier even if you have not uploaded a new image: the meter is on visitors, not images.
  2. The free plan does not go far. Its listing offers a Free plan with all features – For sites with up to 2000 visits /month. You can push it to 22,000 visits, but only by showing Optimole’s badge on your site: generous on features, short on volume, and those extra 20,000 visits cost you a slot on your own page.
  3. They wanted to be able to stop paying. Apart from EWWW’s local mode and ShortPixel’s one-off packs, everything on this list is a subscription.

A visit meter is not automatically a flaw. It is predictable when traffic is predictable. Optimole also names its delivery network — Cloudfront CDN (450+ locations). We publish the size of ours: 335 cities in more than 125 countries.

What happens when you go over Optimole’s visit limit?

Hitting the Optimole visit limit plays out in two very different ways depending on the plan. On the free one, Optimole emails you and gives you a few days to decide whether to upgrade. If you don’t, the official documentation says what comes next: Optimole will return your original images and permanently deactivate your account’s optimized image delivery — your originals come back, and that account’s optimized delivery is switched off for good.

On paid plans nothing gets cut off, and that is precisely the detail. Go over the quota and the subscription climbs on its own to the next tier, with a separate prorated charge processed by FastSpring. The documentation is explicit: Automatic quota upgrades for premium plans cannot be disabled. This is by design. The declared intent is good — your images keep serving without interruption. The side effect is declared too: what decides next month’s bill is your traffic, not you.

Not every tool reacts this way. ShortPixel, compared against Imagify, chose the opposite path: run out of quota and the plugin serves your originals straight from your server until the month resets. Nothing breaks, nothing gets pricier; your site just goes back to its old weight for a few weeks.

What your bill looks like as the site grows

With per-visit billing, the price does not track growth smoothly: it climbs in steps. These are Optimole’s published steps, with the automatic upgrade wiring one to the next:

Visits per monthPlanPrice
up to 2,000Free — or 22,000 showing their badge

The steps are Optimole’s own published monthly prices. The NimboCDN line is not on the same scale — we charge a different unit, a flat $9.90 with no visit meter — it only shows the shape: a bill that does not climb when visits do.

Every step is a price Optimole itself publishes; none is our estimate. NimboCDN is not on that staircase because it charges a different unit — a flat $9.90 a month, with no visit meter — so lining the numbers up compares nothing. What you can compare honestly is the shape of the bill: in one model, a promotion that works or a post that goes viral changes next month’s amount; in the other, it doesn’t.

Where these numbers come from

Every figure on this page was read on the vendor’s own site or its WordPress.org listing on 31 August 2026, and every one is cited at the foot with its link. None of them comes from a review or a comparison site.

Prices move in this market, so the date is worth as much as the number. If you are reading this months later, check the vendor’s page before you decide.

Two things worth a second look if you compare on your own:

  • Smush advertises “up to 500 GB” on its site, but each Pro plan says 50 GB and only Premium says unlimited. The plan card wins, not the headline.
  • Optimole’s visit counts will not match Google Analytics, and their own documentation says why: the two tools measure traffic differently. If you are checking your quota, check it in their dashboard, not in your Analytics.

Optimole opens its pricing page with Boost loading times by 40%. That is Optimole’s claim, not our measurement. NimboCDN reports image bytes instead: page-load time also depends on the hosting, theme and every other resource, so we do not publish a speed multiplier.

Optimole

Who it is for. A large library, predictable traffic and no appetite for configuring anything. You want the CDN, the format conversion and the storage in one place.

It is an image CDN by design, not a compressor with delivery bolted on afterwards, and it shows. All three plans carry Unlimited Images & Sites, Image Offloading & Storage and Unlimited images on all plans with unmetered bandwidth: bandwidth is not metered; visits are. It converts to WebP and AVIF. And it leaves what you have on the server alone — without altering the original files on your server.

PlanPriceVisits per month
Free2,000, or 22,000 while showing their badge on your site
StarterUS$22.90/mo48,000
BusinessUS$47.00/mo120,000
FlexibleUS$109.00/mo300,000

Two things the table does not say out loud. Serving images from your own domain with a CNAME only starts at Business, not at Starter. And the free plan is documented on its WordPress.org listing but does not appear on the pricing page, where only the three paid tiers show.

What it does well

  • An image CDN from birth. Not a compressor with delivery added later, and it shows in how it works.
  • Bandwidth is never metered, on any plan. The size of your library never reaches the bill.
  • It names its network. AWS CloudFront, more than 450 locations.
  • It leaves your originals alone. It works without altering the files you keep on the server.
  • More than 200,000 active installations. Its WordPress.org rating is 4.7.

Where it falls short

  • The meter is on people, not on photos. Cross the visit ceiling and you move up a plan even if you added no images.
  • Paid plans start at 48,000 visits a month. Below that there is only the free tier, at 2,000.
  • Your own CNAME only arrives at Business. On Starter the images come off their domain, not yours.
  • The free plan is not on their pricing page. You have to open their WordPress.org listing to learn it exists.

Verdict. Pick it if your traffic is predictable and your library is large. Skip it if your visits spike: that is exactly where the meter sits, on the part you do not control.

ShortPixel Adaptive Images

Who it is for. Anyone who wants something close to unlimited at a low, fixed price. And agencies, which often prefer buying credit once to carrying yet another subscription.

It is the only one in the group you can pay for in two ways: a monthly plan or a one-off purchase. The unlimited plan is US$9.99 a month, or US$8.33 if you pay yearly, with credits and sites uncapped. The fine print does carry a number, though: 500 GB of CDN traffic a month. The credits never run out; the delivery does.

OptionPriceIncludes
Free100 credits, about 500 visits/month
UnlimitedUS$9.99/mo, or US$8.33 yearlyUnlimited credits and sites, 500 GB of CDN
Unlimited AIUS$15.99/mo, or US$13.33 yearlyThe above plus unlimited AI background removal and upscaling
30K packUS$19.9930,000 credits that never expire, 150 GB of CDN
100K packUS$49.99100,000 credits that never expire, 500 GB of CDN

It serves WebP and AVIF without you doing anything, by swapping image URLs; your original files stay on your server. And if the credits run out mid-month, nothing breaks: its own listing says the plugin will simply serve the original images from your server, without compression or resizing, until the quota resets. The same listing says the delivery network is bunny.net. Worth not mixing up: the Direct Cloudflare integration on its pricing page is a different thing — a token so your own Cloudflare pulls the updated images.

What it does well

  • Subscription or one-off, your call. It is the only one here that offers both.
  • Credits you buy never expire. Useful if your work arrives in bursts rather than every month.
  • Unlimited credits and sites on the Unlimited plan. US$9.99 a month, or US$8.33 paying yearly.
  • Nothing breaks when the quota runs out. The plugin serves your originals straight from your server until the quota resets.
  • It names its delivery network. bunny.net, according to its own plugin listing.

Where it falls short

  • Credits are unlimited; delivery is not. CDN traffic stops at 500 GB a month.
  • A “credit” is a unit of their own. Outside the free plan they do not publish what it converts to in traffic.
  • The least installed of the five. 10,000 active installations of Adaptive Images, well behind the rest.

Verdict. Pick it if you want a fixed monthly price or would rather buy credits once. Skip it if you deliver more than 500 GB a month: that is the published delivery cap.

Imagify

Who it is for. Sites with heavy traffic and few new images. All the more so if you already run WP Rocket, which comes from the same team.

Imagify makes traffic irrelevant by a simple route: it does not deliver anything. It compresses your files and leaves them where they were, on your server. There is no CDN in the product. If you already have one, that is an advantage rather than a gap.

PlanPriceImages per month
StarterUS$0/mo20 MB, about 200 images, 2 MB per image maximum
GrowthUS$5.99/mo500 MB, about 5,000 images, US$5 per extra GB
InfiniteUS$11.99/moUnlimited

Two things before you pick it. The good one: AVIF conversion is in even the free plan — WebP and AVIF conversion included in the free plan — which is more than EWWW and more than my own free plan offer. The one that needs attention: Imagify automatically replaces the original images with an optimized image. There is a backup and a one-click restore, but by default it rewrites your library. That is a different kind of risk from everything else on this list, and it is worth deciding on purpose rather than discovering afterwards.

What it does well

  • Traffic stops mattering. It compresses and leaves the files on your server; it delivers nothing.
  • AVIF even on the free plan. More than EWWW and more than our own free plan give.
  • Unlimited sites on all three plans. The free one included.
  • From the WP Rocket team. It sits well with that cache if you already run it.

Where it falls short

  • There is no CDN. If you do not have one, delivery is still your problem.
  • It replaces your originals. It swaps them for the optimised version unless you turn the backup on yourself.
  • The free plan cuts each image at 2 MB. Larger files do not fit that plan.
  • 4.3 stars, the lowest of the five. Across 1,653 ratings on WordPress.org.

Verdict. Pick it if you already have a CDN or do not need one, and above all if you already run WP Rocket. Skip it if you are uneasy about it rewriting your originals by default.

Smush

Who it is for. Agencies with a fixed, known roster. It is the only one here that charges per site rather than per usage, and that makes it the only one whose bill you can project a year out.

One site is US$50 a year; three, US$75; ten, US$100. The Premium tier covers unlimited sites at US$4.99 a month. Every Pro plan includes 50 GB of CDN traffic, on a network they describe as Global CDN (119 nodes) without saying whose it is. It converts to WebP and AVIF and serves them on its own.

Its free version has a clear limit: In the free version, images over 5MB are skipped. Files above that threshold are left unchanged.

What it does well

  • The only one that charges per site. Next year’s bill is one you already know today.
  • Unlimited sites at US$4.99 a month. On the Premium tier.
  • It converts to WebP and AVIF on its own. With nothing for you to configure.
  • Over a million installations and 4.8 stars. As widespread as Imagify and EWWW.

Where it falls short

  • The free tier skips images over 5 MB. Files above that threshold are left unchanged.
  • It does not say what network is behind its CDN. It describes it as Global CDN (119 nodes) and nothing more.
  • Their site advertises up to 500 GB; the plans say 50. Only the Premium tier says unlimited.
  • Charging per site punishes you for growing. Every new client adds up, whether they use the tool much or not.

Verdict. Pick it if you need to know today what next year’s bill will be. Skip it if your roster grows fast: every new site adds up, heavily used or not.

EWWW Image Optimizer

Who it is for. Anyone who wants to optimise seriously without sending a single file to anybody’s cloud.

EWWW takes a different route: it is, in its own words, the only plugin that lets you optimize images using tools on your own web server. jpegtran, optipng, pngout, pngquant, gifsicle and cwebp, running on your own machine, free. If what bothers you about everything above is the dependency itself, the discussion ends here.

Its paid side is a CDN called Easy IO, billed by bandwidth: US$80, US$160 or US$320 a year for 50, 200 or 400 GB, with unlimited images and sites on all three tiers and overage at US$0.065 per GB on the top one. Check one thing before you pay: AVIF conversion is built into the Easy IO CDN. Here the modern format is not free.

What it does well

  • It optimises without a file leaving your server. It is the only one that uses local tools: jpegtran, optipng, pngquant and cwebp, among others.
  • That local mode costs nothing. Not now and not later.
  • Unlimited images and sites on all three paid plans. US$80, US$160 or US$320 a year.
  • The overage price is published. US$0.065 per GB, instead of forcing you up a tier.
  • Over a million installations and 4.8 stars. With years behind it.

Where it falls short

  • AVIF is paid. It lives inside the Easy IO CDN; in the free local mode it is not there.
  • Charging by bandwidth punishes your good weeks. A post that takes off costs you money without you changing anything.
  • It does not say what network is behind Easy IO. It only names it.
  • It declares a “fair usage quota” without publishing the figure. On the unlimited plans.

Verdict. Pick it if your real objection is the dependency: in local mode nothing leaves your server and it costs nothing. Skip it if you want AVIF without paying.

NimboCDN

Stopping here to say it plainly: NimboCDN is mine. Read what follows with that suspicion in place, and check it against the entries above.

Who it is for. A store that wants no meter on it, where images and traffic can grow without the bill following them.

US$9.90 a month, or US$99 a year. Flat rate. Traffic is never counted.

That is not a commercial promise: it is how the thing is built. Each image is transformed once and stays cached for good. Once the image is cached — every visit after the first — no request reaches the transformation service, and that is measured in the experiment the price was built on. Ten visits and ten million cost the same, because visits were never what we were counting.

What goes into an image CDN and what comes outYour original files enter on the left. The engine detects each image, picks the right width, converts the format, caches the result for good and delivers it.

How an image CDN works on the inside. Each file goes in once, comes out resized and converted, and from then on the cache serves it. That is why traffic stops being a cost variable.
The large original stays inside the server while a much smaller copy travels to the visitor’s screen
The big original stays on your server; only a much lighter copy travels to the visitor. That is how Optimole and NimboCDN work. Imagify replaces the original instead, unless you switch its backup on.

Your original files stay exactly where they are. They are not replaced, not moved, not uploaded anywhere.

You switch the connector off and everything goes back to how it was, in one click. If the service stops responding, the connector stops itself and your platform serves its own images. We tested the four worst cases — origin down, origin slow, corrupt file and invalid signature — and all four end on the original image. Never on a broken one.

On format: at equal perceived quality, measured with SSIMULACRA2 at 70, AVIF came out 32.1% lighter than JPEG at the median, winning on all 14 of the 14 images we tested, taken from two real stores, across 336 encodings. On the 9 images of a real home page, that was going from 2,323 KB to 281 KB.

Worth knowing before you try it. The free plan is a sample, not a usage tier: it covers your home page, up to 50 new images a month, in WebP. It is meant for seeing it work on the page that gets the most visits, no credit card and no commitment.

And if your site is small, or most visits land right on the homepage — the classic landing-page case — that slice covers what matters, and the free plan serves you perfectly well. The whole site and AVIF come with the paid plan, and there the price has no steps: US$9.90 a month, or US$99 a year, with no meter in the middle.

What it does well

  • No traffic meter. Traffic is never counted, on any plan.
  • Each image is transformed exactly once. After the first visit, no request reaches the transformation service. Measured.
  • Your originals stay where they are. Not replaced, not moved, not uploaded anywhere.
  • Reversible, and fail-safe. One click turns it off and everything goes back. If the service does not answer, your platform serves its own images.
  • It stores no visitor data. No IP, no browser, no page.

Where it falls short

  • The free plan covers your home page only. Up to 50 new images a month, where every free tier above covers the whole site.
  • AVIF is paid. On the free plan we serve WebP; Imagify gives AVIF even on theirs.
  • For now the connector is WordPress only. If your store runs on another platform, it is not for you yet.

Verdict. Pick it if you want no meter on you and need images and traffic to grow without the bill following them. Skip it if what you are buying is track record: the connector is new and the other five have years.

Is switching simple? What changes and what doesn’t

Leaving Optimole is simpler than it looks, with one exception worth knowing before you deactivate anything.

If you never used their cloud storage, the exit is clean, and their own documentation says so: on deactivating the plugin, the image URLs will be reverted to the original URLs, and the images will serve from your own server. Your files never moved; what changes is who serves them. If some image still points at the old URL after that, it is cache — the caching plugin’s, the host’s or the browser’s — and clearing it fixes it.

The exception is Image Offloading, the Pro feature that moves your images into Optimole’s cloud. There, order matters: bring the files back first, deactivate second. The official path lives in Settings → Image Storage, choosing “Optimole Cloud and your website” and confirming Transfer back from Optimole; you can also request a ZIP export of the whole library from their dashboard. And keep your domain listed under Allowed Domains until the end — without it, their documentation warns, the rollback won’t run.

On this side, trying costs you nothing. The NimboCDN connector never moves or rewrites a single file — your originals stay where they are — and switching it off returns the site to its previous state in one click. The free plan covers your homepage forever, no credit card, precisely so you can watch it work before deciding. And the number that starts the whole decision is free either way: the image size checker weighs the images your own storefront serves today.

Which one should you pick?

Before the recommendation, the side-by-side of what each one delivers:

  • Lots of images, modest traffic. Optimole. The visit ceiling is precisely the one you will not reach, and with bandwidth unmetered the size of the library stops mattering.
  • Heavy traffic, few images. Imagify, or EWWW in local mode. Paying per visit to serve nine images is the worst possible fit.
  • Both are growing and you want to stop thinking about it. NimboCDN’s paid plan has no cap on visits, images or traffic. ShortPixel stops delivery at 500 GB a month.
  • A fixed roster of clients. Smush. It is the only one whose bill for next year you already know today.
  • No third-party dependencies. EWWW local. Nothing leaves your server and nothing costs anything.
  • You want AVIF without paying. Imagify: AVIF is in even the free plan.

Frequently asked questions

What counts as a visit for Optimole?

Their pricing page defines it as a unique daily user: each visitor counts once, whatever they do and however many times they come back within those 24 hours. Someone opening six pages counts as one. The same someone tomorrow counts as another. There is one documented exception: an unusually large burst of requests from the same source in a short time — a scraper, say — can add more than one visit.

Which of these plugins leaves my original files alone?

Optimole states that it works without altering the originals on your server, and NimboCDN does not touch them either. ShortPixel swaps URLs and serves from its CDN; your originals stay on your server, and get served directly again if the quota runs out. Imagify is the exception: it replaces the originals with the optimised versions unless you enable the backup. If you go that way, set it up before the first pass.

Do I need a CDN, or is compressing enough?

If your audience sits close to your server and your images are already the right size, compressing gets you almost all of the benefit, and both Imagify and EWWW local do it without a subscription. A CDN pays for itself when the audience is spread across the world, or when you want size and format decided per visitor instead of frozen at upload time.

Is it worth moving to AVIF?

On weight, no argument: at equal perceived quality we measured AVIF 32.1% lighter than JPEG at the median, across 14 images from two real stores. On search, be careful what you expect. Google has indexed AVIF since August 2024 with nothing special required, but it was explicit that the format on its own does not improve your ranking. The measured result is a lighter image. We did not measure page-load time or LCP.

What happens if I go over my Optimole plan’s visit limit?

It depends on the plan, per their official documentation. On the free one, Optimole emails you and, with no upgrade within a few days, returns your originals and permanently deactivates that account’s optimized delivery. On paid plans, the subscription climbs to the next tier on its own, with a separate prorated charge — and that automatic upgrade cannot be turned off.

Does Optimole’s badge really add 20,000 visits to the free plan?

It does: the official listing offers 20,000 extra visits for showing their badge, which adds up to 22,000 with the plan’s 2,000. Read the trade for what it is — you pay for those visits with a permanent slot on your own page.

Is there an Optimole alternative with a fixed price and no visit meter?

Yes — that is NimboCDN’s model: a flat $9.90 a month with traffic never counted. Of the other four, the closest is ShortPixel, which does not count visits — but caps delivery at 500 GB of CDN traffic a month.
