An image CDN for the images you already host
Lighter images, faster pages. No files to move.
Change the image URL and every visitor gets AVIF or WebP, sized for their screen, at the lowest quality that still looks like the original. Your dashboard shows exactly how many bytes it saved.
No upload, no SDK, no rebuild. Free tier: 5 GB a month, no card.
How the image CDN works: three steps, and no images to move
Name your origin
Any server that answers HTTPS: your website, or the public address of a storage bucket. Nothing is uploaded.
Swap the hostname
Your images keep their paths. Use the hostname you are given, or your own domain with a CNAME.
Add parameters
Width, format and quality to start. The console shows what every image weighed before and after.

Image transformations, by URL parameter
Every parameter, in the API referenceResize and fit
Box sizes, four ways to fill them, pixel density, and the width the browser says it needs.
w h fit dpr w=auto
The smallest format accepted
AVIF where the browser takes it, then WebP, then JPEG or PNG. Your markup does not change.
f=auto
Quality chosen by measurement
The lowest quality that still looks like the original, decided per image by a similarity score.
q=auto
Placeholders and dimensions
Width, height, colours and a tiny preview as JSON or CSS, so the layout does not jump.
info blurhash thumbhash
Signed URLs
An HMAC signature and an expiry, so nobody can change the parameters or reuse a link forever. Optionally bound to one visitor's address.

AI editing
Crop around the subject, remove the background, upscale, or correct tone and colour. A paid add-on, with monthly credits.

Cut a rectangle, keep a focal point in frame, or trim a uniform border away.

EXIF and other metadata, location included, taken out by default, with wide-gamut colours converted to sRGB first so they survive. Turn it off to keep them.

Turn and adjust
Rotate, mirror, and correct brightness, contrast, saturation and gamma, or blur, sharpen and turn grey.

Rounded, circular, bordered
Rounded corners, a circle cut from the image, or a solid border in the colour you set.

Logos and watermarks
A line of text or a second image from your origin, placed in a corner at the opacity you set.

Presets
Name a set of parameters in the console and use the name in the URL. Anything written in the URL still wins.

Lighter on slow connections
When the browser asks to save data, automatically sized images go out at a lower density and quality.

Purge from your deploy
Drop every cached size and format of an object, or of a whole prefix, with an API key. The console's Cache tab clears every node at once.

AI add-ons
Added to a paid plan from the console's billing page, on the same invoice. Every AI parameter works with each; they differ in monthly credits. A smart crop or tone correction is 1 credit, a background removal 5, an upscale 5 per doubling, and serving a result that is already cached costs nothing.
AI Neural Starter Add-On
$15 a month, on top of the plan
25,000 credits a month
For sites that crop a lot of photographs: smart cropping and automatic tone correction.
AI Neural Pro Add-On
$49 a month, on top of the plan
100,000 credits a month
For catalogues that need cut-outs or larger images: background removal and upscaling.
AI Enterprise Neural Add-On
$199 a month, on top of the plan
500,000 credits a month
The largest allowance, for high-volume workloads.
Charged when added, for the rest of the month. Past the credits, AI requests are refused rather than billed, and removing an add-on credits nothing back. Terms.
Which plan fits?
Every image served counts, from the cache or not. Your console shows both figures for the month so far.

What it does not do
So nobody finds out after signing up.
- It is not storage. There is no upload. Your images stay at an origin you already run.
- Still images only. Video and animation are not transcoded.
- It is not a whole-site CDN. It delivers images. Your pages and scripts stay where they are.
- AI editing is not in any plan. It is a paid add-on with a monthly credit allowance. Results are automated: a crop can miss the subject and a cut-out can have rough edges, so check them before relying on them.
What you can check before you sign up
Where the edge is, right now
Nodes checked in during the last 90 seconds, by region:

Each request goes to the nearest one.
Card payments by Stripe
Checkout and the billing portal are Stripe's own pages. Card numbers never reach this site.
Leave when you like
Cancel from the Billing tab. Delete the account, with its keys, domains and logs, yourself from the Security tab, as the privacy policy describes.
No trackers on this site
No analytics, advertising or session-recording scripts are loaded on these pages.
Open interfaces
The delivery API is a public OpenAPI document, and the framework package is MIT-licensed.
Abuse is reportable
Anybody can report an image delivered through the service, without an account.

All articlesMoving image CDNs without a cutover
Changing image service is mostly a rename. Where the originals live decides the rest, and running both side by side turns a risky switch into a few checked templates and one DNS record.
30 October 2026 · 4 min readnext/image without the built-in optimiser
next/image writes good markup and, by default, resizes on your own server. A custom loader keeps the first and moves the second — which widths Next asks for, and what to set so it asks for the right ones.
30 October 2026 · 4 min readWhat an AI edit actually costs
Credits are charged for inference, not for traffic, so a cut-out shown a million times is paid for once. The rates, a worked catalogue, and exactly when a rendition is charged again.
Questions about the image CDN
Do I have to move my images?
No. ZawCloud fetches each image from your origin the first time it is asked for, transforms it, and caches the result. Your files stay where they are.
What if a browser does not support AVIF?
With f=auto the edge reads the browser's Accept header and sends AVIF, then WebP, then JPEG or PNG. AVIF output is on the paid tiers; the free tier stops at WebP.
How do signed URLs stop hotlinking?
A signed URL carries an expiry in exp and an HMAC-SHA256 signature in sig, made with a key from your console. Change a parameter, or use the URL after it expires, and the edge answers 403. The exact recipe is in the API reference.
Can I use my own domain?
On the paid tiers. Point a CNAME such as img.example.com at your hostname; the certificate is issued and renewed for you.
What does a cache purge clear?
A purge from the console reaches every node, and reports how many answered and how many cached variants each one removed, so a partial purge shows as partial.
Does it work with Next.js, Nuxt or Astro?
Yes, without changing your components. One package, @zawcloud/images,
gives each framework's image component a loader that points at the edge:
Next.js
, Nuxt
and Astro
.
Anything else that writes an <img> tag only needs the URL changed.
What does AI editing cost, and what is a credit?
AI editing is an add-on to a paid plan, from $15 a month with a monthly allowance of credits. A smart crop or a tone correction costs 1 credit, a background removal 5, and an upscale 5 for each doubling. A result that is already cached costs nothing, and past the allowance AI requests are refused rather than billed. The add-ons are under Pricing.
I use imgix, Cloudinary or Cloudflare Images. How hard is moving?
Usually a hostname change and some renamed parameters, because the edge fetches from an origin you already run. Each guide maps the other service's parameters to these: imgix , Cloudinary and Cloudflare Images . Images that live only in Cloudinary have to be exported to storage you host first.
How do I cancel?
From the Billing tab in the console. The plan stays active until the end of the period already paid for.
