Guide & FAQ
Good to know
Can I keep the original proportions?
Yes. The ratio is locked by default, so changing the width updates the height automatically. Unlock it when you need an exact width and height.
Will making an image larger improve its quality?
No. You can make an image larger, but resizing cannot create detail that was not in the original file.
