Crop PDF Pages and Trim Margins Online
Trim the margins off every page of a PDF by a set amount.
How to Crop a PDF in 3 Steps
- Upload your PDF. Drag and drop or browse for the PDF you want to crop. This tool works great for removing excessive white borders from scanned documents.
- Set the crop margin. Enter the margin size in points to trim from each page. A value of 36 points equals approximately half an inch or 12mm — a good starting point for most scanned documents.
- Download the cropped PDF. Click "Crop PDF" and download your trimmed document. The cropped version maintains the same content but with reduced page margins.
Why Use PDFTools to Crop PDF?
- Remove scanner border waste — Eliminate the excessive white space that flatbed scanners add around scanned documents, making pages cleaner and more professional.
- Applied to all pages — The crop is applied uniformly to every page in the document, ensuring consistent margins throughout.
- Print-ready output — Cropped PDFs are often more suitable for printing, with content better centred on the page without unnecessary border space.
- Content is never cut off — The crop adjusts the page boundary (CropBox) rather than cutting into the content area — the tool is designed to remove margin space, not clip text or images.
Frequently Asked Questions
Will cropping cut off any text or images?
PDFTools crops the page margin area. If you set a crop margin larger than the actual white space border, content may be affected. Start with a small value (18-36 points) and increase gradually if needed.
What unit is used for the crop margin?
Margins are specified in PDF points. One inch equals 72 points. Half an inch (a common scanner border) is 36 points. One centimetre is approximately 28 points.
Can I crop only specific pages?
The Crop PDF tool applies the same crop margin to all pages. If you need different margins on different pages, you would need to split the PDF first, crop each section separately, then merge the results.
