Why merge PDFs in your browser?
Most online tools upload your files to a server to combine them. That means your documents — which might hold contracts, IDs, or bank statements — leave your computer. This tool is different: it does all the work on your device, so your files are never uploaded.
- Private: files never leave your computer.
- Free: no account, no watermark, no limits.
- Fast: no waiting in an upload queue.
Tips for a clean merged PDF
- Reorder pages first with Organize PDF if a file is out of order.
- If the final file is large, run it through Compress PDF.
- Need only some pages? Use Split PDF before you merge.
