Q: Are my photos uploaded to a server?

No. Compression runs entirely in your browser using the canvas API. Your photos never leave your device.

Q: Which output format should I choose?

JPG gives the smallest files for photos and is compatible everywhere. WebP is 25–35% smaller than JPG at the same quality and works in all modern browsers — great for websites. Use PNG only when you need transparency.

Smaller images, same device

Oversized images slow down websites, blow past email attachment limits, and get rejected by upload forms. This compressor re-encodes your images locally using your browser's built-in graphics engine, typically cutting photo file sizes by 60–80% at quality levels you can't tell apart from the original.

Because nothing is uploaded, you can compress hundreds of photos in one go — no queue, no daily limit, and no copy of your pictures sitting on someone else's server.
