About This Tool
Automatically crop whitespace margins from PDF pages with our free online auto-crop tool. Intelligent content detection removes excess borders and blank areas, creating optimized files compatible with Adobe Acrobat Reader and all PDF viewers.
Our smart algorithm analyzes each page to detect content boundaries and automatically determines optimal crop margins. Adjust sensitivity settings to fine-tune detection for documents with varying backgrounds or light content near edges. Process single pages or entire documents at once.
All auto-crop processing happens locally in your web browser. Your documents never upload to external servers, ensuring privacy for scanned contracts, technical drawings, financial statements, and any PDFs requiring automatic margin removal.
Perfect for cleaning up scanned documents with inconsistent borders, removing excessive whitespace from academic papers, optimizing PDFs for e-reader displays, or preparing images for extraction. Works with all PDF formats including scanned images, Adobe Acrobat files, and documents from Microsoft Office and scanning software.
