PDF Cropper
Crop document margins or resize pages in PDF files client-side. Fully offline and secure inside your browser.
What is PDF Cropper?
The PDF Cropper allows you to crop PDF page margins to remove white borders, headers, or adjust the visible area. Clean up slides or resize pages to make them fit mobile displays, e-readers, or print templates.
How Does PDF Cropper Work?
It updates the `/CropBox` or `/MediaBox` values inside the page dictionary of your PDF structure locally. This changes the visible boundaries of the page instantly without resizing or rendering pixels.
How to Use PDF Cropper — Step by Step
- Drag your PDF document into the active workspace.
- Use the visual adjustment box to define the crop area on the preview page.
- Choose whether to apply this crop to all pages, odd/even pages, or just the current page.
- Click 'Crop PDF' and download your adjusted file.
Key Benefits
- Clean Borders: Easily trim away scanner noise, black borders, or empty margins.
- Perfect Fit: Customize page sizes for Kindle, tablet displays, or specific printer settings.
- Data Safety: Operates client-side, securing your confidential drafts.
Who Uses PDF Cropper?
- Mobile E-Readers: Crop massive margins off textbooks so the text reads larger on small screens.
- Slide Prep: Crop presentation slides to extract diagrams, charts, or images.
Tips & Best Practices
- Apply crop to a sample page first before cropping all pages to ensure no text is cut off.
- Use the 'Auto-Crop' option if available to automatically trim empty white space margins.
Common Mistakes to Avoid
- Cropping too close to the text, which might cut off letters when printing.
- Forgetting that cropping in PDF hides content but does not delete it from underlying binary layers.
