Smart compression

Per-image quality settings, no human involved

We’ve built an AI that picks the right amount of compression by looking for an artefacts. Combine it with auto format selection, and you’ve got the best compression to quality ratio on the market

Smart resize

Generate missing background

When there is a drastic change in the aspect ratio, just stretch the background. Smart CDN distinguishes the objects to keep them untouched.

Smart crop

Keep what matters in the frame

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