How to crop a PDF
To crop a PDF, open the Crop PDF tool, add your file, set how much to trim from each edge, and download — PDFER adjusts every page's crop box in your browser, with nothing uploaded.
How cropping works
Cropping sets the visible area of each page by trimming the margins, so scanners' black borders and excess whitespace disappear. The underlying content isn't deleted, so it prints and displays within the new bounds.
Pair it with resize or rotate
After cropping, use Resize to scale pages to a standard size, or Rotate first if a scan came in sideways.
