How to merge PDF files
- Drop your PDF files into the box above.
- Drag them into the right order.
- Click Merge and download the combined PDF.
Merging without re-rendering
The pages are copied into the new file exactly as they are: text stays text, links and fonts stay intact, and nothing is compressed again.
PDFs that are protected against editing (but open without a password) can be merged too.
Frequently asked questions
Is there a limit on files or size?
No fixed limit. Your device's memory is the only constraint; a few hundred pages is no problem on a normal computer.
Are my files uploaded anywhere?
No. The conversion runs inside your browser on your own device. The files are never sent to a server, so nobody else can see them, and they're gone when you close the tab.
Is it really free?
Yes: no sign-up, no watermark, no daily limit and no ads. Because the work happens on your device, there are no server costs to pass on.
