Crop PDF page margins to eliminate printer registration marks, excess white borders, or focus on specific content areas across all pages.
Unlike conventional PDF websites that send your personal tax forms, legal agreements, and corporate contracts to third-party cloud infrastructure, PDFolio operates under a Zero-Server Architecture. Your documents are decoded into pure memory buffers (Uint8Array) inside your browser's dedicated JavaScript runtime or Web Worker. When you click download, the newly assembled PDF is produced directly from memory into your Downloads folder.
Frequently Asked Questions
Does cropping delete the underlying text?
Cropping adjusts the visual viewport (CropBox/MediaBox). Standard PDF readers will only display the cropped area.
