Crop PDF Free Online: Trim Margins from PDF
Trim PDF margins by percentage: crop top, right, bottom, and left from every page or a page range.
Trim whitespace, headers, or footer bands from scanned PDFs, research papers, or multi-page exports. Control each margin independently as a percentage of the page size, and scope the crop to a page range so cover pages stay full-bleed.
How to Use It

- Download the result: Download the processed file directly to your device.
Frequently Asked Questions
What percentage should I use?
Start with 3-5 percent for narrow margin trimming. Go up to 15-20 percent to remove running headers or footer bands from scanned documents.
Does cropping delete the trimmed content?
No. The crop box is a view hint. Viewers like Adobe Reader show only the cropped region, but the original page content is preserved. You can uncrop later.
Can I crop only selected pages?
Yes. Use the page range field to scope the crop to specific pages. Leave it empty to crop the entire document.
Is the PDF uploaded to a server?
No. Crop PDF runs entirely in your browser using pdf-lib. The source PDF contents are not uploaded for supported processing workflows.
