FAQ
Are my images uploaded to a server?
No. Every operation runs entirely inside your browser using WebAssembly and on-device models. Your files never leave your device and are never sent anywhere. You can even disconnect from the internet after the page loads.
Which format gives the smallest file?
AVIF is usually 30-80% smaller than JPEG at the same visual quality, followed by WebP. Use JPEG or PNG only when you need maximum compatibility.
Is there a file-size or batch limit?
No. Because everything runs locally, you can compress as many images as your device can handle, with no size cap.
