Frequently asked questions

Can I enlarge an image with this tool?

Yes — set a percentage above 100%, but for big enlargements the Upscale tool gives a sharper result.

Will resizing keep the aspect ratio?

In percentage and longest-side modes, yes. Only "exact width × height" can distort the image if you pick a different ratio.
