How to use Crop PDF

  1. Add the PDF

    Drop in the document and check the preview.

  2. Choose the unit

    Points (72 per inch) for exact amounts, or percent of the page size.

  3. Enter the margins

    Set how much to trim from the top, bottom, left and right. The same margins apply to every page.

  4. Check, then download

    Open the downloaded file and look at the edges. If a page is left with nearly nothing, the tool stops and says which one.

When to use Crop PDF

  • Trimming the wide margins from a scanned page
  • Cutting a header or footer band off every page
  • Preparing pages for a reader on a small screen
  • Removing the border added by a printer driver

FAQ

No. It sets the page’s visible area (the CropBox), and the rest of the page stays in the file, where a PDF editor can bring it back. Do not rely on cropping to remove sensitive information.
No. The same margins apply to every page. Split the document first if you need separate crops.
The tool stops and names the page that would be left with almost nothing visible, and does not produce a file.
No. The content outside the box is kept, so the file is about the same size.
The original file is untouched. Keep it, and crop again from it if you need different margins.

About Crop PDF

A PDF page has several boxes. Cropping here sets the CropBox, which is the area a viewer displays and a printer prints. The rest of the page is not erased.

That has a consequence worth knowing: the trimmed content is still in the file, and anyone with a PDF editor can extend the box and see it. If you need to remove something, use Edit PDF to black it out.

Margins are measured from the page as shown, so a page rotated in the file is cropped from the edges you actually see.

Tips and limits

  • Crop a little less than you think, then adjust. The tool does not show a live crop box.
  • 36 points is half an inch.
  • Use percent when pages differ in size.
  • Never rely on cropping to hide confidential information.
