How merging works
Combine several PDF files into one document, right in your browser.
Files are processed locally on your device — nothing is uploaded to a server.
Add files in the order you want them; the merged PDF follows that order.
The result downloads as a single PDF you can save or share.
Very large or password-protected files may take longer or fail to process.
Frequently asked questions
How do I merge PDF files into one?
Add the PDF files you want to combine, drag them into the order you need, then download a single merged PDF. It’s free with no sign-up or watermark.
Can I reorder the files before merging?
Yes. Arrange the files in any order before merging, so the pages appear exactly how you want in the final document.
Are my PDF files uploaded to a server?
No. Merging happens inside your browser — your files never leave your device and nothing is uploaded or stored.
Is there a limit on how many PDFs I can merge?
There’s no account or watermark. Very large or numerous files use more memory, so a laptop is more reliable for big merges.
