Crop PDF

Remove unwanted borders and whitespace from every page in your PDF.

Select a PDF file to begin. Set crop margins in points for each side.

What is the Crop PDF?

PDF cropping is the process of removing unwanted margins, whitespace, or borders from the edges of PDF pages. By setting crop dimensions (measured in points, where 1 point = 1/72 of an inch), you define the visible area of each page, effectively trimming excess space while preserving all content within the crop area.

How it works

Upload your PDF and specify crop margins in points for each side: top, right, bottom, and left. A value of 0 means no cropping on that side. The tool applies these margins uniformly to every page, adjusting the visible area without compressing or distorting the remaining content. You can then download the cropped PDF instantly.

  • Precision control—set exact margins in points (1 point = 1/72 inch) for consistent results across all pages
  • Universal application—margins apply to every page in your PDF simultaneously
  • Whitespace reduction—cleaner, more professional documents without wasted space
  • Instant processing—crop completes in seconds, even for large files
  • Preserve quality—no recompression or content distortion, only the visible area changes
  • Free and private—browser-based, no sign-up, files deleted after download

Tips & common mistakes

Common mistakes

  • Setting crop margins larger than the page dimensions, causing an error—always verify your margins fit within the page size
  • Cropping content accidentally by setting margins too aggressively—preview carefully if the document has important edge text
  • Forgetting that margins apply to all pages—if pages differ in size or layout, some may crop unexpectedly; check beforehand
  • Confusing points with inches or millimetres—remember 1 point = 1/72 inch, so 72 points = 1 inch

Tips

  • Start with small margins (10–20 points) if you're unsure; you can reprocess the PDF with larger margins if needed
  • For scanned documents, use the same margin value on all sides (e.g., 50pt all around) for a clean, symmetric look
  • Calculate margins using: desired margin (inches) × 72 = points; e.g., 0.5 inch = 36 points
  • If you need different margins on different pages, crop once for all pages, then edit individual pages with a PDF editor

Frequently asked questions

What are points in PDF measurement?

A point (pt) is a unit of measurement in typography and PDF documents. 1 point = 1/72 of an inch. So 72 points = 1 inch, 36 points = 0.5 inches, and 12 points ≈ 0.17 inches. Use this conversion to set accurate margins.

Will cropping reduce my file size?

Slightly. Cropping removes the data for margins and borders, which may reduce file size by a small amount, but the main benefit is a cleaner document, not smaller files. The reduction depends on how much whitespace is removed.

Can I crop different amounts on each page?

This tool crops uniformly across all pages with the same margin values. If you need page-specific cropping, you'll need a full PDF editor or use this tool on pre-split files, then recombine them.

What if my PDF has pages of different sizes?

The tool applies the same margins to all pages regardless of size. If pages differ significantly, some may be cropped more aggressively than others. Inspect the result carefully and consider normalizing page sizes first if critical.

Can I crop password-protected PDFs?

Not directly. If your PDF is encrypted, you'll need to unlock it first using an unlock tool, then crop the unencrypted version.

How do I undo cropping if I set the margins wrong?

The original file is unchanged; simply reprocess the original PDF with different margin values. Alternatively, use your browser's undo or reupload the file if needed.
