How to Crop PDF Pages
This tool reduces the visible page area by trimming the same margin from each side. It is useful for scanned documents, exported slides and PDFs with excessive whitespace.
Example
If an A4 scan has about 20 points of empty border on every side, entering 20 trims that outer area from each page and produces a tighter layout.
Factors That Affect the Result
The crop amount must be smaller than half the page width and height. Mixed page sizes, uneven scan borders and content near the edge can make a single margin value unsuitable for every page.
Frequently Asked Questions
Does cropping delete the original file?
No. A new PDF is created.
Is hidden content permanently removed?
The crop box changes the visible area; underlying content may still exist outside it.
Can I use one margin for all pages?
Yes, this version applies one value to every page.
How the Tool Works and Its Limits
Cropping a PDF changes the visible page region but may not permanently delete content outside the crop boundary in every PDF workflow. Sensitive information should be properly redacted rather than merely cropped, and page boxes should be checked before sharing.
