Quickstart
Your first optimized image
Five steps, no image migration. You keep your origin exactly as it is.
1. Sign in and add your site
Sign in with an email code, create a workspace, and add the domain your images are served from today — for example www.example.com, or a path like example.com/images if your images live under one folder.
2. Verify you control the domain
Ownership is required before we will fetch anything from your origin. Choose either method shown in the dashboard:
- DNS TXT record — add the provided record to your domain’s DNS.
- Verification file — host the provided text file, containing exactly your token, at the shown
/.well-known/path.
Click Check. Once verification passes, your site is ready to activate.
3. Get your CDN hostname
The dashboard assigns a hostname that looks like cdn12345.cdn.mn. This is where your optimized images are served from. See Your CDN hostname for details.
4. Rewrite your image URLs
Swap the host in your image URLs for your CDN hostname and keep the same path:
Before: https://www.example.com/photos/hero.jpg
After: https://cdn12345.cdn.mn/photos/hero.jpgAdd parameters to resize on the fly. The best modern format (AVIF or WebP) is chosen automatically from the browser — you don’t pass a format:
https://cdn12345.cdn.mn/photos/hero.jpg?w=768
https://cdn12345.cdn.mn/photos/hero.jpg?w=480&dpr=2&fit=cover5. Confirm it’s working
Load a rewritten URL in your browser. The first request pulls and optimizes the original; the next is served from cache. In the dashboard’s test panel you can preview any image served through your CDN hostname. To compare original bytes against optimized bytes, run your page through the website analyzer.
That’s it — point more URLs at the hostname as you’re ready. When you change an image at your origin, purge it so the next request re-pulls the new version.
