What cropping means in a PDF
A PDF page carries two frames. The first describes the whole sheet as it was produced. The second says which part of that sheet should be shown. Cropping only touches the second: you tighten the display frame, you do not cut the sheet.
So content that falls outside the frame does not disappear. It stops being displayed and printed, but it stays in the file, and restoring the display frame to its original size brings all of it back. Any PDF editor can do that.
This is not a limitation of this tool, it is what cropping means in the format itself. A service promising you otherwise would either be misleading you or doing something other than cropping.
Margins are given in points
PDF measures in typographic points: seventy-two points to the inch, so about twenty-eight points to the centimetre. An A4 page is 595 points wide by 842 tall, a Letter page 612 by 792.
You enter the four margins to remove — top, bottom, left, right — and the same crop applies to every page of the document. Trimming thirty points off the top of a scan cuts a little over a centimetre.
If the margins you ask for would leave nothing to display, the operation is refused rather than producing a blank page.
When it is the right move
Cropping solves presentation problems, not confidentiality ones. The cases where it is exactly what you need:
- A scanned document that kept the scanner's margins, often grey or skewed, around the useful page.
- A print-oriented PDF you want to read on an e-reader or tablet, where every centimetre of margin is a centimetre of text lost.
- A slide deck exported to pages with a repeated banner you would rather not see.
When it is not enough
If what sits outside the frame must stay secret — a name in a header, an amount in a footer, a distribution marking — cropping protects nothing. The text is still there, it copies out, and it comes back in one move.
The right gesture then is redaction, which actually removes the content, or deleting the whole page if the page itself is the problem.
Common questions
Are my files uploaded to the internet?
No. This tool runs entirely in your browser: the document is opened on your device, processed there, and never sent anywhere. You can even go offline once the page has loaded.
Is the cropped content really deleted?
No, and this matters: cropping moves the visible frame, and content outside it stays in the file. To erase for good, use redaction.
Is it free, and do I need an account?
Free and unlimited, with no account and no sign-up. This tool costs us nothing because it runs on your machine, so we have no reason to ration it.
