Merge PDF Files
Combine several PDF documents into a single file. Add your files, put them in the right order, then merge — everything happens in your browser, so your files are never uploaded to a server.

Frequently asked questions
Is it safe to merge PDFs with this tool?
Yes. Your PDFs are processed entirely in your browser using JavaScript. They are never uploaded to our servers, so nobody else can access them.
How many PDF files can I merge at once?
There is no fixed limit. The practical limit depends on your device's memory — most computers can easily merge dozens of files or several hundred pages.
Can I change the order of the pages?
You can reorder whole files before merging using the up and down arrows. Pages inside each file keep their original order.
