How to Merge or Split PDFs Online — Free & Private
This tool uses pdf-lib, a pure JavaScript PDF library, to merge and split PDFs entirely inside your browser. No file is ever uploaded to a server. Your documents stay on your device.

- 📎Combine contracts, reports, or scans into a single shareable file
- 🔀Reorder pages before merging using the ▲▼ buttons
- 📊See the total page count before you download
Split / Extract pages
- ✂️Extract a chapter, section, or specific pages into a new PDF
- 📦Split every page into its own PDF — downloaded as a ZIP
- 🔢Use ranges like "1-5, 8, 12-15" for precise extraction
Frequently asked
Are my PDFs private? Yes — processing is 100% client-side. Files are never sent anywhere.
Does it work with scanned PDFs? Yes. Scanned PDFs (image-based) merge and split just like any other — the tool handles them as pages, not text.
What about password-protected PDFs? Lightly encrypted PDFs often work; heavily password-protected files will fail with an error.
Is there a file size limit? No hard limit — but very large PDFs (100 MB+) may be slow depending on your device's memory.
