Why Crop PDF Pages?
Cropping removes unwanted margins, headers, footers, or edge content from your PDFs. It's essential for cleaning up scanned documents and focusing on specific content areas.
Common Cropping Tasks
- Remove Margins: Trim excess whitespace from scanned documents.
- Focus Content: Isolate specific sections for presentations or excerpts.
- Print Preparation: Adjust margins for proper printing alignment.
- Clean Scans: Remove scanner artifacts and uneven edges.
Crop vs Resize
Cropping removes content from edges without scaling. Resizing changes page dimensions and scales content. Use cropping for margin adjustment, resizing for page size standardization.
常见问题
How do I crop a PDF?
Upload your PDF, set the crop margins using the sliders or enter values manually, choose which pages to crop, and click Crop PDF to download.
Can I crop specific pages only?
Yes, you can choose to crop all pages uniformly or select specific pages to crop while leaving others unchanged.
Will cropping reduce file size?
Cropping sets a visible area but doesn't remove the cropped content internally, so file size may not decrease. Use our Compress PDF tool for size reduction.
What is auto-crop?
Auto-crop automatically detects content boundaries and removes excess whitespace from all edges, useful for trimming scanned documents.
Is cropping PDFs free?
Yes, our PDF crop tool is completely free with no registration, watermarks, or hidden fees.
Can I undo a crop after saving?
The downloaded PDF has the crop applied. Always keep your original file as a backup if you might need to adjust the crop later.
How do I remove white margins from scanned PDFs?
Use auto-crop to automatically detect and remove white margins, or manually set equal margins on all sides to trim whitespace uniformly.
Can I crop to a specific page size?
For precise page size changes, use our Resize PDF tool. Cropping is best for trimming margins and removing unwanted edge content.
Will cropping affect links and text?
Links and text within the visible crop area are preserved. Content outside the crop boundaries will be hidden but links may still be clickable.
Can I preview the crop before applying?
Yes, you can see a preview of your crop settings before downloading the final cropped PDF.
