Crop the margins of a PDF

Choose a PDF or drop it here

Processed on this device. Nothing is uploaded.

Short answer

Drag four sliders and watch a live preview of the first page as the margins come in. The crop applies to every page and is written into the file, so other readers see the same trimmed area.

Doing more than one thing?

The full editor puts every operation in one workspace with undo, so you are not exporting and re-opening between each step. Same engine, same privacy, still nothing uploaded.

Why this one does not upload your file

Almost every free crop the margins of a pdf tool works by sending your document to a server, doing the work there, and sending a result back. That is a cost decision rather than a privacy one — server time costs money, which is why those tools meter you, ask for an account, or cap your file size.

This one runs the same work in your browser using JavaScript, so your file never travels anywhere. There is no upload step, no queue, no account, and no page limit — and the page keeps working if you disconnect from the internet partway through.

You do not have to take that on trust. Open your browser's network tab and watch while you work, or read how it works.

What happens to your file

  • It is read from your disk into this tab's memory
  • Every change happens on your own processor
  • The result is built in memory, reopened and checked before you are offered it
  • Your original file is never modified
  • Closing the tab releases everything — nothing is stored
Questions

Straight answers

Does cropping delete what was in the margin?
No. It reduces the visible area; the content is still in the file and can be restored by anyone who changes the crop back. Never use it to hide something.
Can I crop pages differently?
Not yet — the crop applies to every page. Extract the pages you want to treat differently, crop them separately, then merge.
Why would I crop a PDF?
Usually to remove wasted white margins before printing, or to trim scanner edges and shadows from a scanned stack.
