Frequently Asked Questions
How do I crop a PDF page?
Upload your PDF to a crop tool, drag the crop handles to define the visible area, and download. The tool adjusts the CropBox — the rectangle defining what viewers display. Content outside the crop area is hidden but not deleted from the file.
How do I remove white space from a PDF?
Use a PDF crop tool with auto-detect margins. The tool analyses the content bounding box on each page and sets the CropBox to fit snugly around the content, removing empty margins. Manual crop also works — drag the handles inward from all sides.
Can I crop a PDF to a custom size?
Yes. Enter exact dimensions (width × height in mm, inches, or points) in the crop tool to set a precise CropBox. This is useful for creating PDFs to specific standard sizes (e.g. A5, business card) or for custom print trim sizes.
How do I crop a scanned PDF?
Scanned PDFs often have large white margins from the scanner bed. Use a crop tool's auto-detect feature to find the actual document boundaries, or manually drag the crop area to exclude the scanner margins. The underlying scan image is not modified.
What is the difference between crop and trim in PDF?
In the PDF specification, CropBox is the visible viewing area, TrimBox is the intended final page size after printing and trimming (used in print production), and BleedBox includes bleed areas beyond the trim. Everyday 'cropping' adjusts the CropBox. TrimBox and BleedBox are PDF/X production concepts.
