About This Tool
PDF cropping removes unwanted whitespace and oversized margins from document pages, making them easier to read on screen or to prepare for specific printing requirements. Scanned documents often have large black borders or uneven margins introduced by the scanning hardware; cropping eliminates these and produces a clean, focused page. Academic papers, ebooks, and reports downloaded from publisher sites frequently carry wide margins that make reading on tablets unnecessarily small — cropping fixes this immediately.
JustConvert's crop tool lets you specify exact margin sizes in points for each side independently (top, bottom, left, right). The changes are applied to every page of the document, and the resulting PDF is immediately available for download. No page content is lost — the crop simply adjusts the visible area of the page.

Frequently Asked Questions
What units are the crop margins specified in? expand_more
Margins are specified in PDF points, where 72 points equals one inch (approximately 28.35 points per centimetre). A value of 72 for the top margin would remove one inch from the top of every page.
Does cropping remove actual page content? expand_more
Cropping adjusts the PDF media box, which defines the visible area of the page. Content that falls outside the new boundaries is hidden but not deleted. In some PDF editors you can restore the original boundaries; however, JustConvert trims the actual content box for a clean, final output.
Can I crop individual pages differently? expand_more
The current tool applies the same crop margins to all pages. If you need different crops for different pages, split the document first, crop each section individually, and then merge them back.
Why would I need to crop a PDF? expand_more
Common reasons include: removing thick black borders from scans, reducing oversized margins on academic papers for better tablet reading, standardising page sizes when combining documents from different sources, and preparing print-ready PDFs that fit specific paper dimensions.
Will the file size change after cropping? expand_more
Cropping adjusts the viewable area of the page but does not re-encode image data. File size typically stays the same or decreases only slightly.
