Questions and answers

Which format should I choose?

WebP gives the smallest files at the same quality and works everywhere on the modern web. Choose JPG for maximum compatibility and PNG when you need transparency or pixel-perfect graphics.

How does “target size” work?

The tool tries different quality levels and keeps the best one that fits under the size you set. If even the lowest quality is too big, scale the image down.

Are my images uploaded?

No. Everything is encoded in your browser, so even private images stay on your device.
