Frequently asked questions

Will cropping delete content?

Cropping hides anything outside the new page box — it stays in the file unless you flatten, but viewers and printers only show the cropped area.

Can I resize to a standard paper size?

Yes — A4, Letter, Legal and custom dimensions, with optional scaling of the content.
