How does client-side image compression work?

The tool draws your image into an HTML5 Canvas element in your browser and re-encodes the pixel matrix using browser-native compression algorithms at your designated quality setting.

Are my private photos uploaded to your server?

No. Unlike other online converters, processing happens 100% locally on your computer or mobile device. Your files never leave your device.

Which image format provides the best compression: JPEG or WebP?

WebP generally provides 25% to 35% smaller file sizes than JPEG at equivalent visual quality, while supporting transparency.
