FAQ
What unit are the crop values in?
Values are in PDF points. 1 point = 1/72 inch. So 72 pt ≈ 1 inch, and 28 pt ≈ 1 cm.
Does cropping remove content permanently?
Cropping adjusts the visible area (media box) but does not delete the underlying content. The original data is still in the file.
Is my PDF uploaded to a server?
No. All processing is done entirely in your browser using pdf-lib. Your file never leaves your device.
