Fix PDF Margins — change page margins and size, free and private

Change PDF margins and paper size so a document prints inside the page instead of getting cut off at the edges. Everything runs in your browser, so no document contents are sent to PaperFit.

How to fix PDF margins

  1. Drop your PDF into the box above, or click to choose a file.
  2. Pick a paper size (A4, Letter, and 9 more) and set the margins you want.
  3. Turn on fit-to-page scaling or blank-page removal if you need them.
  4. Click Apply — the page resizing happens locally, in your browser.
  5. Download the corrected PDF. No document contents are sent to PaperFit.

What it does

  • 11 paper presets, from A4 and Letter to Legal and A5
  • Fit-to-page scaling that shrinks content so nothing is clipped on print
  • Smart content detection to tighten or even out uneven margins
  • No watermark, no sign-up, no document contents sent to PaperFit

Common uses

  • Fixing a PDF whose text gets cut off at the edge when printed
  • Resizing a document from Letter to A4 (or back) before sending it abroad
  • Adding a binding margin so a report prints cleanly for hole-punching

Is it private?

Yes. Unlike most "change PDF margins online" tools, PaperFit processes your file on your device, and no document contents are sent to PaperFit. Adjusting margins and paper size happens entirely on your own device, so a contract, form, or printable you're preparing stays with you. You can confirm it: open your browser's network tab and watch — no document contents are sent to PaperFit while you fix the margins.

Frequently asked questions

Are my files uploaded to a server?

No. Margin and paper-size changes run in your browser. No document contents are sent to PaperFit, so there is nothing for us to see or store.

Will it crop my content or just add space?

It does both safely: you can add margins (which pads the page) or use fit-to-page scaling to shrink the content so nothing is clipped. Smart content detection helps even out uneven margins without cutting text.

Which paper sizes can I set?

There are 11 presets including A4, Letter, Legal, A3, and A5, so you can match whatever printer or portal expects.

Can it remove blank pages?

Yes. Blank-page removal drops empty pages while it adjusts the rest, which is handy for cleaning up scans before printing.

Is there a file size limit?

You can process PDFs up to 200 MB. Because everything runs locally, very large files depend on your device's available memory.

Is it free, and does it work on mobile?

Yes to both. It's free with no account and no watermark, and it runs in mobile browsers too, though very large files are limited by phone memory.
