Add image border

Pixelate image

Dimensions, format and file size are different changes

Check the destination’s requirements first: specific pixel dimensions, a compatible format or a smaller file. Work on a copy so you can compare the result with the original.

Change dimensions

Keep aspect ratio so a rectangular image retains its shape when reduced.
