Images transformed

Charged when Sizy renders an image at a given size and set of parameters.

$0.40
per 1,000 transforms

Images delivered

Every image request Sizy answers, at any volume. Not metered, not billed.

Free
however many you serve

Every account starts free

5,000 transforms every month, on every account, on top of delivery never being billed at all. No card required to start — you are only charged for transforms above the allowance.

Compare

What would you actually pay?

Every image CDN bills on a different axis — credits, bandwidth, unique transformations, 8KB cache units — which makes them almost impossible to compare from the rate cards. Put your numbers in once.

The set actually served this month, not everything you own

Every request answered, across all visitors

KB

KB after resizing — used to price the bandwidth-metered vendors

That works out to 152.6 GB delivered and 1.5 GB stored — the figures the credit-based and bandwidth-based vendors actually bill on.

Sizy

Pay as you goCheapest

$0.40/1,000 transforms after 5,000 free — delivery is not billed at any volume

No monthly fee, no minimum, and neither delivery nor storage is metered. Fair use on delivery is about 500 per transform per month, which a normal site does not approach.

$6.00
/ month

Cloudflare Images

Pay as you go

$0.50/1,000 unique transformations after 5,000 free

Delivery is not billed when transforming images from your own origin, so only transforms count here. Requires images to be reachable from a zone on Cloudflare.

$7.50
/ month

Vercel

Pro

$20/mo including $20 credit, then $0.05/1K transformations plus 10 cache units per image

Only works for sites deployed on Vercel — not a standalone image CDN you can point at an existing site — and the $20 plan is unavoidable to get it. If you already pay for Pro, most of this is on your bill either way.

$20.00
/ month

imgix

Starter

195.6 credits — 1 per 500 renders, 1/GB delivered, 2/GB stored

Cheapest plan once its own overage rate is applied. Advanced and AI renders cost more credits than the standard rate used here.

$48.91
/ month

ImageKit

Lite

152.6GB delivered and 1.5GB stored — transformations are not billed separately

Billed on bandwidth rather than on transform count, so cost tracks image weight more than image count.

$65.29
/ month

Cloudinary

Plus

174.1 credits — 1 credit is 1,000 transformations, 1GB storage or 1GB bandwidth

Cheapest plan whose included credits cover the usage. Credits are consumed by transformations, storage and bandwidth together.

$99.00
/ month

Sizy is cheapest for this workload

At 20,000 distinct images and 2,000,000 deliveries, Sizy comes to $6.00 — no monthly fee, no minimum, and the deliveries are not billed at all, so that figure does not move when your traffic does.

Our row is not typed in here

It is calculated by the same module that produces your invoice, so this table cannot quote a price we do not charge.

Your originals stay where they are

Every figure assumes the shape Sizy is built for: transforming images that already live on an origin you own. Where a vendor prices that differently from hosting your originals, the front-your-own-origin case is the one costed.

The cheapest plan that fits, never the one they would sell you

For vendors with tiers, the model picks the least expensive plan that covers the usage — including where a larger plan's cheaper overage beats a smaller plan's lower base.

Where a vendor publishes no rate, there is no number

Cloudinary lists no overage price at any tier, so past its largest published plan the table says so rather than estimating. A guess dressed as a figure would be worse than a blank.

One assumption, stated rather than buried

Vercel bills a cache read only when an image is not already cached in the visitor's region, which no rate card can tell you. The model assumes a tenth of deliveries need one. It is the only figure here not published by somebody.

What is left out

Video, asset management, AI features, custom domains, SSO and support agreements. Several of these vendors sell far more than image resizing, and if you need those things the price of the resizing is not the decision.

When Sizy is the wrong choice

  • A very large catalogue served lightly. ImageKit meters bandwidth rather than transforms. If you have a quarter of a million distinct images and modest traffic against them, you are paying us per image for something they charge per gigabyte for, and the gigabytes are small.
  • You are already paying for Vercel. Their image optimisation is part of the hosting plan rather than something you buy, and the table above includes that $20 because there is no way to get the feature without it. If you already pay it, subtract it — the images themselves cost them very little, and that is hard to argue with. It is also not an option at any price for a site that is not on Vercel.
  • You fit inside someone's free tier. Cloudinary and ImageKit are both more generous than us at the very bottom. If you fit and expect to stay there, take it.
  • You need more than resizing. No video, no asset manager, no AI editing, no custom domain, no SLA, no procurement paperwork.

How billing works

A transform is what Sizy renders
A transform is one image rendered at one size and set of URL parameters. Change a parameter and you have asked for a different transform. Every parameter is listed in the docs.
A transform is billed once per month it is used
Rendered images are kept until the end of the calendar month — or for seven days, whichever is longer — and then cleared. So a URL you keep serving costs one transform each month rather than one forever, and a URL nobody asks for again costs nothing after it is cleared. Serving it any number of times in between is delivery, not another transform. The seven-day floor is there so that starting on the 28th does not mean paying for the same images twice in your first week.
One URL is one transform, whatever the format
Sizy serves AVIF or WebP to browsers that accept them and the source format to the rest. Each format is stored separately so caches keep them apart, but the URL is billed once — you are not charged again because a visitor arrived in a different browser.
Delivery is free, and not metered
Every image request Sizy answers is a delivery, and none of them are billed — at any volume. Serving one image a million times costs exactly what serving it once costs, which is nothing. The only line on your invoice is transforms. Fair use: we will get in touch above roughly 500 deliveries per transform per month, a ratio a normal site does not come close to.
Invoiced monthly, in arrears
Usage is totalled at the end of each month and invoiced. Nothing is charged up front, and there is no monthly platform fee.
Bring your own source
Sizy fronts a source you already own — an S3 bucket, a CDN, or any public URL. Your original images stay where they are; there is nothing to migrate and nothing to re-upload.
