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.

Will resizing reduce quality?

Downscaling uses stepped high-quality resampling, so results stay sharp. Enlarging always invents pixels and is off by default.

Can I resize many photos to the same width?

Yes. Enter the width, leave the height blank, and every image is scaled proportionally to that width.
