Complete Guide: How to Crop PDF Pages
Cropping PDF pages removes unwanted margins, headers, footers, or blank spaces, making your documents more compact and professional. This is especially useful for scanned documents with excessive white space.
Upload Your PDF
Select the PDF file you want to crop. The document loads with a visual preview of each page.
Select Pages to Crop
Choose which pages to crop. You can crop all pages uniformly or select specific pages for individual cropping.
Define Crop Area
Drag the crop handles on the preview to define the area you want to keep. Everything outside this area will be removed.
Apply Crop Settings
Review the preview to ensure the crop looks correct. Adjust if needed, then click 'Crop PDF' to process.
Download Cropped PDF

Pro Tips
- Use 'Apply to All Pages' for uniform cropping of scanned documents.
- Leave a small margin (5-10mm) to avoid cutting off content accidentally.
- Crop before printing to save paper and ink.
Common Issues
Content got cut off?
Undo and adjust the crop area to include more space. Use the zoom feature to precisely position the crop boundaries.
Crop not applying to all pages?
Ensure 'Apply to All Pages' is checked if you want uniform cropping across the entire document.
