PDF Book Page Trimmer — Crop Left/Right Pages & Export
This free online tool helps you remove unwanted margins from scanned book PDFs by applying separate crop settings for left and right pages. Perfect for digitizing your book collection, creating eBooks for Kindle, or preparing scanned documents for professional printing. You can preview each page with visual crop lines, copy settings across multiple pages, and export selected pages to JPG, PNG, TIFF, or WebP at your chosen resolution.
How It Works
Our PDF trimming tool uses advanced server-side processing with PyMuPDF to deliver professional-quality results. Here's how to use it:
- Upload your PDF: Select a scanned book PDF from your computer. We support files up to 100MB in size.
- Adjust crop settings: Choose between Left Page or Right Page mode and use the intuitive sliders to set trim percentages for each side (left, right, top, bottom). Red lines show left page crops, blue lines show right page crops.
- Preview in real-time: Navigate through your PDF pages and see exactly how the crop will look with visual overlay lines on each page.
- Copy settings efficiently: Use "Copy to All Pages" or "Copy to Remaining" buttons to apply your current page's crop settings to multiple pages at once.
- Select pages to export: Choose which pages you want to include in your final output—useful for skipping blank pages or unwanted content.
- Configure export options: Select your preferred image format (JPG, PNG, TIFF, or WebP), adjust quality settings (1-100), and set DPI (72-600) for print or screen use.
- Process and download: Click "Process PDF" and receive a ZIP file containing all your cropped pages with sequential numbering.

Example Use Cases
Scenario: Digitizing a Children's Book
You've scanned a vintage children's book that has wide margins and visible binding gutters in the center of each spread. The left pages have more margin on the left side, and right pages have more on the right.
Solution: Use our tool to set different left/right crop settings. Set left page trim to remove more from the left edge (e.g., 10%) and center (e.g., 50%), then set right page trim to remove more from the right edge and center. Copy these settings to all pages, preview the results, then export as high-quality JPGs at 300 DPI for a clean digital version.

Frequently Asked Questions
Q: Are my files uploaded to your server?
Yes, files are temporarily uploaded to our secure server for processing using PyMuPDF. However, they are immediately deleted after export and never stored permanently. See our Privacy Policy for details.
Q: Can I crop left and right pages differently?
Absolutely! That's the main feature of this tool. Use the Left/Right page selector to switch between settings and adjust each side independently.
Q: What if my PDF has single pages instead of spreads?
Enable "Single Page Mode" at the top of the crop settings. This treats each PDF page as a full page and only uses the left page crop settings across the full width.
