FAQ

Can I crop all pages or just specific ones?

You can crop all pages uniformly by setting margin values, crop selected pages, or draw a custom crop area per page in custom mode.

Does cropping remove content permanently?

Cropping adjusts the visible area defined by the CropBox. The underlying content outside the crop region may still exist in the file but will not be visible. For permanent removal, enable the MediaBox update option.

What is the difference between margin crop and draw crop?

Margin crop removes a fixed amount from each edge in millimeters. Draw crop lets you visually draw the area to keep on a page preview, giving you precise pixel-level control.

Can I use different crop areas for each page?

Yes. In custom crop mode, you can set and save a unique crop area for each page individually before processing the entire document.

Will text near the edges be cut off?

That depends on the crop values you set. Review the page preview after drawing or entering margins to confirm no important content falls outside your selected crop area.
