Merge PDF

Your files never leave your device.
How it works
1. Add two or more PDF files. 2. Use the ↑ and ↓ buttons to arrange them — pages are merged in the order shown. 3. Click “Merge PDFs” and download the combined file. The merging runs entirely in your browser using the open-source pdf-lib library; no file is uploaded to any server.
Good to know
Is there a limit? No page or file limits from us — the only limit is your device's memory. Very large files work best on a desktop browser.
Will bookmarks and links survive? Pages are copied exactly as they are. Some internal links and bookmarks that pointed between the original separate files may not carry over.
