PDF documents define five boundaries that control the imaging process: the Crop Box, Bleed Box, Trim Box, Art Box and Media Box. PDF-Tools uses these boxes to determine areas when the Crop Pages feature is used. Use the Apply to Box dropdown menu, detailed below, to display the editing boxes in the preview pane, then click and drag boxes and/or use the number boxes to adjust their dimensions. Further information about editing boxes is available here. The following options are available in the Crop Pages dialog box:
•Click Show All Boxes to view the Crop Box, Bleed Box, Trim Box and Art Box in the preview pane. (Please note that the Bleed Box, Trim Box and Art Box use the same dimensions as the Crop Box by default.
•Use the Crop Method dropdown menu to determine the crop method used:
•Manual Margin Control enables the user to determine the cropping margins. Click the text of menu entries in the Apply to Box dropdown menu to view them in the preview pane. Click and drag boxes in the preview pane, or use the number boxes, to adjust their dimensions.

Select this option to remove cropped content from the file.
