How to Crop a PDF Step by Step

Open Crop PDF and choose your file. Work from a copy if the document is important, because that gives you a clean fallback.

Look through the thumbnails before setting the crop. Documents made from scanners often have slightly different margins from page to page, while exported reports usually have consistent margins.

If you are new to the terms, read what PDF cropping means before applying a crop to a long document.

Drag the crop boundary inward until the unwanted border or white space is outside the visible area. Leave a small safety margin around text, signatures, page numbers, and stamps.

Avoid cropping exactly to the edge of text. A few pixels of breathing room prevents clipping in PDF viewers and printers.

Apply the crop to all pages only when the document has the same margin pattern throughout. For mixed scans, crop page by page or in smaller groups.

If your main goal is margin cleanup, the remove PDF margins guide explains how to choose a safe boundary.

Download the cropped PDF and open it in a normal viewer. Check the first page, a middle page, the last page, and any pages with tables, signatures, or page numbers.

If the output still looks wrong, use crop PDF troubleshooting to identify the cause.
