How to crop a PDF

  1. Choose your PDF, or drop it onto the box. It opens in your browser, so the file never leaves your device.
  2. Drag the edges or corners of the blue box on the preview. The shaded part is what will be cut away. Drag inside the box to move it.
  3. Or type the amounts to trim from the top, right, bottom and left, in millimetres or inches.
  4. Check the other pages with the arrows, then click Crop PDF and download.

You get a new copy named yourfile-cropped.pdf; the original is untouched. Rotated and landscape pages are cropped the way they look on screen.

Crop all pages or just one

All pages trims the same amount from every page, which is what you want for scans and documents where every page has the same margins. If one page is smaller than the rest and the crop would leave almost nothing of it, the tool tells you which page.

Only page … crops just the page in the preview and leaves the rest as they are. To give a few pages different crops, crop one, download, open the new file and crop the next.

How to remove white margins from a PDF

Click Remove white margins. The tool looks at every page, finds where the text and pictures stop, and fills in the trim amounts so the crop ends just outside the content, with a small gap so nothing touches the edge. It uses the same crop for every page, small enough that nothing on any page is cut, which keeps the pages looking even.

This is handy for slides saved as PDF, papers with wide margins that you want to read on a phone or e-reader, and charts or drawings that need tight edges. It only removes white space: a grey or black scanner border counts as content, so drag the edges in by hand for those.

Cropping to an exact size

Cropping can only make a page smaller. To reach a size, subtract it from the page you have and split the difference between the two sides. An A4 page is 210 × 297 mm and a US Letter page is 215.9 × 279.4 mm (8.5 × 11 in).

What to type for common crops
You wantStarting pageTrim
½ inch off every edgeAny12.7 mm (0.5 in) on all four sides
A5 from the middle of the page (148 × 210 mm)A431 mm left and right, 43.5 mm top and bottom
A square page (210 × 210 mm)A443.5 mm top and bottom
A4 width (210 mm)Letter2.95 mm left and right
Letter height (279.4 mm)A48.8 mm top and bottom

The status line under the preview shows the size each page will end up, so you can check before downloading. One inch is 25.4 mm.

Example: trimming the border off a scan

A 12-page document scanned with a dark edge down both sides

  1. Open the PDF and leave All pages selected.
  2. On page 1, drag the left and right edges of the box in until the dark strips are shaded. Say the boxes now read 9 mm left and 11 mm right.
  3. Step through a few pages with the arrows. Scans drift a little, so make sure no page has text inside the shaded part; ease the edge out if it does.
  4. Click Crop PDF and download. All 12 pages lose the same strips and print with clean edges.

Does cropping delete anything?

No. Cropping a PDF hides the edges rather than cutting them off: PDF readers show and print only the area you kept, but everything outside it is still in the file. That has three consequences:

  • Don't crop to hide private information. Anyone with a PDF editor can bring the hidden part back. Black it out with proper redaction instead.
  • The file doesn't get smaller. Use Compress PDF for that, or Delete PDF pages to drop whole pages.
  • Printers may enlarge cropped pages. “Fit to page” scales the smaller page up to fill the paper. Choose “Actual size” in the print settings to print at the real size.

Frequently asked questions

How do I crop a PDF without Adobe Acrobat?

Open it in the tool above, drag the box or type how much to trim, and click Crop PDF and download. It works in any modern browser on Windows, Mac, iPhone or Android, with nothing to install.

Can I undo a crop?

Keep your original file and you can always start again. The cut-away edges are still inside the cropped PDF too, so a PDF editor that changes page boxes can bring them back.

Can I crop a PDF on my phone?

Yes. Drag the round handles with your finger, or type the amounts in the boxes if the page is small on screen.

Is my PDF uploaded?

No. The PDF is opened, cropped and saved by your browser, so it never leaves your device. There is no watermark and no sign-up.
