Frequently asked questions
Is it safe to merge PDFs online?
With this tool the files never leave your device: they're combined by pdf-lib in your browser, so nothing is uploaded or stored on a server.
How do I combine PDF files into one?
Add two or more PDFs, put them in order, and click Merge. You'll get a single PDF named after the first file.
Can I merge only certain pages from each PDF?
Yes. Each file has a Pages box. Type ranges like 1-3, 5 to include just those pages, or leave it empty for all of them.
Can I merge password-protected PDFs?
Not directly. Remove the password with Unlock PDF first, then merge the unlocked copy.
