Privacy
Your images stay in your browser. There is no backend, no remote storage and no cookies. Local storage is used only to remember your compression preferences.
Local processing
Images are decoded, resized and re-encoded entirely on your device using the browser Canvas and Web Worker APIs. Nothing is uploaded.
Storage
Only your mode, maximum size and output format preferences are saved in localStorage. Reloading or closing the page discards your files and results.
Fonts and assets
The Inter font is self-hosted, so the page makes no external network requests for assets.
