Merge PDF
Combine multiple PDFs into one file, right in your browser. Reorder before merging; nothing is uploaded.
Runs in your browser — files never leave your device
How it works
Add the PDFs you want to combine, order them, and download a single merged file.
Everything happens locally, so even confidential documents stay private.
Frequently asked questions
- Are my PDFs uploaded?
- No. The merge runs in your browser with pdf-lib; the files never leave your device.
- Can I control the order?
- Yes — use the up/down arrows to arrange files before merging.
