Frequently asked questions

How do I keep the proportions?

Tick "Keep aspect ratio" and fill in only width or height.

Will enlarging reduce quality?

Making an image bigger can make it look soft, since new pixels are estimated.

Which format is best?

JPG for photos, PNG for graphics, WebP for the smallest size.
