Crop PDF

About this tool

Crop PDF trims excess white space from the edges of every page, tightening a document that was scanned or exported with big margins. It is useful for making a PDF feel intentional rather than padded, or for fitting more content on screen. The tool reduces the page size by the margin you specify, in your browser, so the file stays private on your device. We are honest that cropping changes the page box rather than resampling the content, so extremely large crops may clip elements near the edge — check the result before you rely on it. The original is left untouched and a new cropped file downloads to your machine. No account, no upload. For tidying scanned pages or shrinking awkward margins, it is a quick, private fix.

Awkward margins make a PDF look sloppy. A scanned book page comes with huge white borders that waste screen space. An exported diagram has padding that pushes content off-center. A photographed document includes finger edges you want gone. A report exported from a tool adds margins that look like mistakes. Cropping tightens all of these so the page reads as intentional. Doing it locally keeps the document — possibly containing personal or business detail — on your device. We caution that cropping changes the page box, so an aggressive value can clip something near the edge; a quick look at the result prevents surprises. For everyday tidying of scans and exports, it is a fast, private fix that makes the file look the way it should. A quick preview confirms nothing important was clipped before you send the tightened copy. The trimmed copy keeps your original intact, so you can always go back to the unmodified file if needed.

How it works & privacy

Enter a margin in points and press Run. The tool opens your PDF in the browser with pdf-lib, shrinks each page box by that margin, and downloads the cropped result. Nothing is uploaded. Cropping adjusts the page boundaries, so very large values can clip edge content — preview before trusting the output.
