Frequently asked questions
Can I crop just the first page?
Yes — uncheck "Apply this crop to all pages" to crop only the first page, leaving the rest of the document untouched.
Does cropping delete content permanently?
Cropping sets the page's visible area (crop box) — content outside the selection is hidden from view in standard PDF viewers.
What if my pages are different sizes?
The crop area is applied proportionally, so it scales correctly even if pages in your document differ slightly in size.
