Keep your images. Change the hostname.
Make your website images lighter without moving your image library. After verifying your domain, change the hostname in your image URLs. CDN.MN fetches the originals, optimizes them and delivers cached versions through a global edge network.

Verify your origin first. We fetch on a cache miss and serve cached versions on later requests. Illustration, not a speed measurement.
Keep your existing image paths
Verify a domain you control and configure the origin. You receive a CDN hostname, then replace the hostname in your image URLs while keeping their paths. The CDN fetches an original on a cache miss. Your origin must remain reachable, and domain verification is required before delivery begins.
Send the size the page actually needs
Use the supported width, height, fit and device-pixel-ratio parameters to generate suitable variants for cards, product pages and responsive layouts. Format and quality are selected automatically. Correct image dimensions and responsive markup still matter: a CDN cannot know the intended layout of every page.
Measure before and after
Start with the website analyzer to see the image weight on a page. After integration, verify response types and dimensions, test key layouts and compare loading metrics. Use cache purge when an original changes. Improvement depends on the original files, network and page design; there is no fixed percentage promised.
How to get started
- Analyze a representative page and verify your origin domain.
- Replace image hosts in your templates or let a scoped agent make the change.
- Check delivery, layout and loading speed, then use purge when originals change.
Frequently asked questions
Do I need to re-upload my image library?
No. Pull-through delivery fetches images from your verified origin when needed. File hosting is a separate workflow for files you choose to upload.
Can it resize images?
Yes. Supported URL parameters control dimensions, fit and device pixel ratio. See the URL parameters reference for accepted values and examples.
Will an image CDN guarantee a better search ranking?
No. Smaller images can help loading performance, but rankings depend on many factors, including useful content, indexing and overall page experience.
