Are my images uploaded?

No. Images are decoded, processed and re-encoded by your browser on your own device. They are never sent to a server, and closing the tab discards them.

Can I process several images at once?

Yes. Add as many as you need (up to 50), then download them one by one or all together as a ZIP file.
