Questions

What’s the difference between Fit within and Fill and crop?

Fit within keeps the whole image inside your box, so one side may be smaller. Fill and crop covers the box completely and trims what doesn’t fit.

Why didn’t my small image get bigger?

“Don’t enlarge” is on by default. Turn it off if you really want upscaling.

Does resizing keep transparency?

Yes for PNG and WebP. The output keeps the input format unless you choose another; JPG fills transparency with a color you pick.

Are my images uploaded?

No. Everything runs in your browser; images are never uploaded.
