Nothing is uploaded. The file stays in this tab.
Scanned pages often arrive with an inch of empty paper round the edge, and slides exported to PDF bring their own borders. This trims a margin off every page at once, and shows you what you’re keeping before you commit.
Using Crop PDF, step by step
- 01
Drop in a PDF.
- 02
Set how much to take off — one number for all four edges, or a number per edge.
- 03
Check the preview, then crop and download.
What people use it for
- Trim the white border off a scan so the content fills the page.
- Cut the margins down before printing, to get more onto each sheet.
- Even up pages that were scanned slightly off-centre.
What goes in, and where it goes
- What it accepts
- One PDF at a time, of any page size. Trims are set as a percentage, so one setting works across a document that mixes page sizes or orientations. Each edge can take up to 45%, which means a page always keeps at least a tenth of its width and height.
- What you get back
- One PDF with every page trimmed by the amounts you set. Page count, order and rotation are unchanged, and nothing is re-encoded.
- Where your file is processed
- Crop PDF runs in your browser, and so does the preview — the page you see is rendered in this tab, not on a server. The file is never uploaded, and nothing is kept once you close the tab.
Common questions
Does cropping delete the part I trim off?
No. Cropping changes the box a viewer draws, so the trimmed area stops being displayed — but it is still inside the file, and anyone who resets the box gets it back. Do not use cropping to hide private information. It is not redaction, and we would rather say so plainly than let the word “crop” imply otherwise.
Can I crop pages by different amounts?
Not in this version. The amounts you set are applied to every page. If part of a document needs different treatment, split it first, crop that part, then merge it back.
Why percentages instead of millimetres?
Because one setting then works on a document whose pages are not all the same size. Ten percent off the top means the same thing on A4, on letter, and on a page that was scanned sideways — which a fixed measurement would not.
What happens to pages that were scanned sideways?
The edges you pick are the edges you see. “Top” means the top of the page as it appears on screen, whichever way the page is stored inside the file, so a rotated scan crops the way you expect rather than the way the file happens to be written.
Can I turn the preview off?
Yes. It is on by default because cropping without seeing the page is guesswork, but rendering a big or complex page takes a moment, so you can switch it off if you already know your numbers.
