How it works

1. The image is decoded in the browser and rasterized into raw pixels.
2. Pixels are streamed to a dedicated worker powered by the Squoosh mozjpeg/WebP encoders compiled to WebAssembly.
3. If a codec is unavailable, the app falls back to the canvas encoder so everything still runs locally without network calls.
