About this tool

Crop PDF — trim page margins, free and private

Crop a PDF to cut away unwanted white margins or scan borders — drag the handles to set the crop box, or let it auto-detect the content. It runs entirely in your browser, so no document contents are sent to PaperFit.

How to crop a PDF

  1. Drop your PDF into the box above, or click to choose a file.
  2. Drag the crop handles on the page, or pick a preset — auto-detect content, or A4/Letter center.
  3. Choose whether to apply the crop to one page or to all pages.
  4. Click Crop — the crop box is set locally, in your browser.
  5. Download the cropped PDF. No document contents are sent to PaperFit.

What it does

  • Visual drag handles to trim margins exactly where you want
  • Presets to auto-detect content edges or center on A4/Letter
  • Lossless crop — sets the page crop box without re-rendering, so text stays sharp and selectable
  • No watermark, no sign-up, no document contents sent to PaperFit

Common uses

  • Removing wide white margins from a scanned document before printing
  • Trimming the dark border off a scan so the content fills the page
  • Cropping a slide deck exported to PDF down to just the slide area

Is it private?

Yes. Unlike most “crop PDF online” tools, PaperFit processes your file on your device, and no document contents are sent to PaperFit — the crop happens on your own device using your browser. That matters when the pages you’re trimming are scanned IDs, signed contracts, or financial statements: they simply stay with you. You can confirm it: open your browser’s network tab and watch — no document contents are sent to PaperFit while you crop.

Frequently asked questions

Are my files uploaded to a server?

No. Cropping runs in your browser. No document contents are sent to PaperFit, so there is nothing for us to see or store.

Does cropping delete the content outside the box?

Cropping sets the page’s crop box, which hides everything outside it rather than re-rendering the page — so text stays sharp and selectable. If you need to permanently strip the hidden content, run the result through the Flatten tool.

Can I crop every page at once, or just one?

Both. Set the crop box and choose to apply it to the current page or to all pages — handy when a whole scan has the same margins.

What does auto-detect content do?

It finds the edges of the actual content on the page and snaps the crop box to them, trimming the surrounding white space for you. You can still nudge the handles afterward.

Is there a file size limit?

You can crop 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 — no account, no install, and no watermark. It runs in mobile browsers too, though very large files are limited by phone memory.
