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.
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.
What a URL can ask for
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
Crop where the subject is
Cut a rectangle, keep a focal point in frame, or trim a uniform border away.
crop fp trim
Signed URLs
An HMAC signature and an expiry, so nobody can change the parameters or reuse a link forever.
exp kid sig
Bot and hotlink shield
Refuse other sites and the crawlers you choose, from the console. On the paid tiers.
A console settingMetadata removed
GPS position, camera serial numbers and timestamps taken out before the image leaves the edge.
strip_exif
Logos and watermarks
A line of text or a second image from your origin, placed in a corner at the opacity you set.
watermark overlay
Measured, not claimed
What the edge recorded over the last 30 days, across every account. A figure with nothing behind it is left out.

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 in preview, and not sold. Subject cropping, background removal and upscaling run only on nodes where a model has been installed. Elsewhere the parameter is refused with an error, rather than ignored.
Questions
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.
How do I cancel?
From the Billing tab in the console. The plan stays active until the end of the period already paid for.
