Frequently Asked Questions

Does cropping a PDF permanently delete the trimmed content?
No. In accordance with the PDF specification, cropping modifies the visible page viewport (CropBox). The content outside the crop box is hidden during display and printing, but remains present in the PDF's internal stream. If you need to permanently sanitize confidential text or data, use FolderBit Redact PDF.
Does cropping a PDF reduce image quality?
No. Cropping only defines new bounding box coordinates (CropBox) for page display. The underlying vector graphics and image streams are not compressed or re-encoded.
What unit of measurement does the crop tool use?
FolderBit uses standard PDF typographic points (1 pt = 1/72 inch, approximately 0.3528 mm). Handy quick presets are provided for 0.5 in and 1.0 in margins.
Can I crop different pages with different margins?
You can choose to crop all pages uniformly, only the first page, or specify exact page ranges like '1-5, 8'.
