Frequently asked questions
How do I preserve the aspect ratio?
Set Height in pixels to 0. The tool calculates height from your chosen width and each source image’s proportions.
Can I apply one size to multiple photos?
Yes. Up to 20 images use the same width and height settings. A nonzero height forces that rectangle and can distort a differently shaped source.
