Auto-cropping reduces the visible area of a page leaving just enough for its contents. For example, if a page contained only a photograph and a caption with a large empty border, after auto-cropping the empty space would be trimmed away, leaving just the image and its caption.

  1. Choose Pages > Auto Crop.
  2. Choose a page range over which to apply the crop.
  3. Press OK.
  4. You can undo a crop by choosing Pages > Remove Crop.
Notes
  • Cropping does not remove anything from a PDF, it just limits what is displayed by PDF viewers and printers.
