Answers

Frequently asked questions

How do I keep the image from stretching?

Enable the aspect-ratio lock. Changing either dimension updates the other to preserve the source proportions.

Can I resize an image larger than its original?

Yes, but upscaling may make the result look softer. Use dimensions appropriate for the intended display size.
