How PDF merge works
This tool reads each file in your browser, combines all pages in order, and generates a new PDF. No server upload required — great for privacy and speed.
- —Keep related invoices or reports together.
- —Combine multiple scans into a single document.
- —Prepare PDFs for emailing or archiving.
How split / extract works
Extract a subset of pages — like pages 3–5 — from a larger PDF. Ideal when you only need part of a report or want to share a section without sending everything.
- —Extract only the relevant section of a longer PDF.
- —Share specific chapters or sections with clients.
- —Reduce file size by removing unneeded pages.
Note: This tool does not bypass passwords or DRM. For locked files, first unlock them using the PDF Password Remover.
Is my data safe?
All PDF processing happens entirely in your browser using the pdf-lib library. Your files are never uploaded to any server — they stay on your device throughout the entire process.
