When to Crop a PDF
📱
Optimize for Mobile Reading
Large margins make text tiny on phone screens. Crop them away to make the content fill the screen for a much more readable experience.
🖨️
Remove Scanner Borders
Flatbed scanners often add a thick black border around the scanned area. Crop it off to produce a clean, professional-looking document.
📊
Isolate a Chart or Diagram
Need just the graph or diagram from a full-page PDF? Crop heavily on all sides to isolate the visual for presentations or reports.
📝
Reduce Whitespace-Heavy Documents
Academic papers and legal documents often have excessive margins. Crop them to fit more content per screen when reading on a tablet.
Common Mistakes & Pro Tips
Crop precisely for the best results.
✗
Confusing crop with compression
Cropping changes the visible page area. It will NOT significantly reduce file size. To reduce file size, use our PDF Compressor after cropping.
✗
Cropping too aggressively
Start with small margin values. Over-cropping can cut into actual text content. Since your original is never modified, simply re-upload and try again with smaller values if needed.
✓
Pro tip: Crop then compress
For maximum results, crop the margins off first, then run the output through our PDF Compressor. This gives you the smallest, cleanest result.
Frequently Asked Questions
How do I crop a PDF?
Upload your PDF, set the crop margins for top, bottom, left, and right, then click Crop. Your cropped PDF will download instantly with the new page boundaries.
Can I crop all pages at once?
Yes, the crop settings are applied uniformly to all pages in your PDF document. You cannot currently crop individual pages differently.
Will cropping reduce file size?
Cropping removes visible content but may only slightly reduce file size, as the underlying PDF data may still be present. For significant size reduction, use our PDF Compressor after cropping.
Can I undo a crop?
The tool creates a new downloaded file — your original is never modified. If you cropped too much, simply re-upload the original and adjust the margins.
What units are used for crop margins?
Margins are specified in points (PDF units) or pixels depending on your input. Generally, 1 inch = 72 points. Start with small values (e.g., 20-30) and preview before making larger adjustments.
Will cropping remove hidden content?
Technically, PDF cropping sets a crop box that hides content outside the boundary, but the content is still present in the file. For permanent removal of content beyond the crop area, you would need a full PDF editor.
Is my file secure?
Yes. All processing happens in your browser. Your file is never uploaded to or stored on our servers.
