Are my images uploaded anywhere?

No. Every tool runs inside your browser using Web Workers and WebAssembly. Files never leave your device, and there is no server, account or tracking.

How much smaller will my image get?

Typically 60–80% smaller for camera JPGs at quality 80, with no visible difference. Converting to WebP saves another 25–35%.

Can I compress to an exact file size?

Yes. Switch to “Target size”, enter the size in KB, and the quality is searched automatically to land just under it.

Why did my PNG barely shrink?

PNG is lossless, so there is little to remove. Choose WebP or JPG as the output format for much smaller files.
