Crop PDF Margins

PDF cropping changes the visible crop box. Enter the amount to hide from each edge in millimetres rather than dragging approximate screen coordinates.

How it works

PDF cropping changes the visible crop box. Enter the amount to hide from each edge in millimetres rather than dragging approximate screen coordinates.

Choose the right inputs

The margins are applied relative to the current crop box. Existing cropped documents therefore receive an additional inset from their currently visible area.

Understand the output

Page coordinates are not automatically relabelled after rotation. On rotated source pages, top and left refer to the underlying PDF coordinate frame.

Use the result carefully

Hidden material remains in the file and can reappear if another program expands the crop box. Cropping is unsuitable when the purpose is permanent removal of sensitive content.
