Image optimization service
A developer API that searches for the lowest quality setting a viewer can’t tell apart from the original, and keeps colours accurate.

The problem
Fixed quality settings either waste bytes or visibly damage images, and colour profiles are often dropped, so photos shift colour. Measuring each result and converting profiles properly solves both.
What it does
- AVIF, WebP, JPEG and PNG, picking the best format each browser accepts
- A visually lossless mode that measures every result against the original
- Colour profiles converted to sRGB
- On-the-fly resizing from signed, expiring URLs
- Smart crop, auto-rotation, retina sizes and blurred placeholders
- Batch processing, cache pre-warming, API keys, usage tracking and rate limits
- Wide-colour (P3) output
- Animated images
- Load testing
