Crop PDF
Crop PDF trims unwanted margins and edges from your pages by setting a new visible page area, applied either to a single page or across the whole document.
About Crop PDF
Cropping earns its keep with scans and slide decks. A book page photographed on a flatbed carries a dark gutter and a lot of dead white space; a slide exported to PDF often has borders that waste screen area on a tablet. Trimming the margins makes the text larger relative to the page, which is a real readability gain on a small e-reader screen.
One important point about how PDF cropping works: it sets the visible page area rather than deleting what lies outside it. Anything trimmed away is still present in the file and can be restored by anyone who changes the crop box back. That is fine for tidying margins, and completely unsuitable for hiding sensitive material. For that, use Redact PDF, which destroys the underlying content.
How to crop pdf
- Upload the PDF you want to trim, or drag it into the box.
- Set the crop margins for the top, bottom, left and right edges.
- Click the crop button and let the tool rebuild the pages.
- Download the cropped PDF and check a page with a wide margin.
Why use this tool
Precise margins
Enter exact trim values for each edge instead of dragging a rough box, which keeps every page in the document cropped identically.
All pages or some
Apply one crop across the whole file, or target specific pages when a scan has a stray oversized sheet in the middle.
Content untouched
Cropping adjusts the page boundary only, so text stays selectable, images are not recompressed and quality is exactly as it was.
