Technical details

AmberPic uses WebAssembly to run compression codecs directly in your browser. For JPG we use MozJPEG, for PNG we use OxiPNG, and for WebP/AVIF we use the official codecs from Google and Alliance for Open Media. All processing happens in your device RAM — nothing is ever sent to any server.

Frequently asked questions

Will I lose quality when compressing?
It depends on the format. JPG and WebP use lossy compression, but you can control the quality level (0-100). PNG uses lossless compression, so there is no visual quality loss.
What is the file size limit?
100MB per file, up to 100 files per batch. This is enough for the vast majority of use cases.
