Smart compression

Per-image quality settings, no human involved

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

50–60% smaller file size compared to the most popular open-source solutions

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.
