Merge PDF files, free, in your browser
Combine several PDFs into a single document, in the order you choose. Everything happens on your device, and the files are never uploaded. That's the difference between this and every tool that makes you hand your documents to a server.
Nothing is uploaded
Your PDFs are combined in the browser. Open DevTools → Network and watch. No file leaves your device.
Your order
Drag files up and down before merging; the output follows exactly.
No account, no watermark
Free, unlimited, and the merged file is clean, with no stamp added.
How it works
Drop your PDFs
Add two or more files.
Set the order
Move them up or down until it's right.
Merge & download
One combined PDF, built on your device.
Questions
How do I merge PDF files for free?+
Drop your PDFs in, arrange the order, and download the combined file. It's free and runs entirely in your browser, and nothing is uploaded.
Are my PDFs uploaded to a server?+
No. The merge happens on your device. Most online PDF mergers upload your files; this one doesn't. You can verify it in the Network tab.
Is there a file limit or watermark?+
No watermark, and no account. Very large batches are limited only by your device's memory.
