When to crop a PDF
- Remove wide white margins so pages read better on a phone or tablet.
- Keep only one part of a page: a receipt on a scanned A4 sheet, a figure, or a ticket.
- Cut off printer marks or a scanner's dark border.
How it works
A frame appears on the page preview. Drag the frame or its handles around the part you want to keep, then choose All pages or This page only. "Whole page" resets the frame. Text and pictures are not re-compressed, so the quality doesn't change.
Different crops on different pages
Crop one page with This page only, download the result, open it again and crop the next page.
Cropping is not redacting
Cropping hides the area outside the frame: readers and printers show only what you kept, but the hidden part is still inside the file. Never crop to remove private information such as an account number. Use Redact PDF, which removes it for good.
For photographed documents, Scan to PDF finds the page edges for you and straightens the page at the same time.
