Uploadcare CDN is not just a cache: we offer integrated image processing with AI-optimized image compression and smart transformation features.

Get started
Smart compression

Per-image quality settings, no human involved

Our AI analyzes an image and adds the correct compression level just before visual artifacts appear. Combine it with auto format selection, and you’ve got the best compression to quality ratio on the market.

Smart resize

Generate missing background

Extreme resize ratios won’t affect objects. The Smart CDN algorithm will detect the background and stretch it accordingly.

Smart crop

Keep what matters in the frame

Make any image fit your layout without losing meaningful parts. Smart CDN detects faces, objects, and corners to set the cropping frame.
