Frequently asked questions
Is this PDF crop tool free?
Yes, completely free with no usage limits, no account required.
How are margins measured?
In points (pt). 72 pt = 1 inch ≈ 25.4 mm. So 36 pt is about 0.5 inch (12.7 mm).
Does cropping delete content outside the crop box?
No. We change the visible area (cropBox), the original content remains in the file but is not rendered.
Will my PDF be uploaded to a server?
No. Cropping happens in your browser with pdf-lib.
Does it work offline?
Yes, after the first visit.
