Frequently asked questions
How do I know exactly how much to crop without clipping content?+
Err on the side of leaving 5-10 extra points. You can always run the crop again if the first attempt leaves too much whitespace.
Can I apply different crops to different pages?+
Currently the same crop is applied uniformly to all pages or a specified range. Run multiple passes for different crops per section.
Will a tight crop cause issues in some PDF viewers?+
Most modern PDF viewers handle tight CropBoxes correctly. If a viewer shows content clipped, try reducing the crop values slightly.
