Will my image be stretched?

Not unless you choose "Stretch". By default the proportions are kept, and with only a width or a height entered the other side is calculated.

Can I make an image bigger?

Yes, by turning off "Do not enlarge small images". Enlarging cannot add detail, so the result will look softer.

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.
