Frequently Asked Questions
Everything you need to know about cropping PDF files
What does Crop PDF do?
Crop PDF trims the visible page area by updating the crop box on each PDF page. This hides unwanted margins without rasterizing the document.
What units does the crop tool use?
Crop values are entered in PDF points. 72 points equals 1 inch.
Does cropping permanently delete hidden content?
No. This tool adjusts the PDF crop box, which changes the visible page area. Hidden content may still exist in the PDF file.
Will the page quality change?
No. The tool keeps the original PDF content as vector/text data and only changes the visible page boundary.
Are my files uploaded to a server?
No. Cropping runs locally in your browser using pdf-lib, so your PDF stays on your device.
