How it works

1.Your image is loaded into an in-memory browser canvas without uploading to any remote server.
2.The HTML5 canvas engine re-encodes the image at your selected quality level and modern compression codec (WebP/JPEG).
3.The compressed binary blob is generated locally on your device for instant download.
