Combine PDF files into one, free

Merging puts several PDFs into a single document in the order you choose — chapters into a book, scans into one file, or invoices into one attachment. Drop your files in, drag them into place or sort them A–Z, and download one clean PDF. Everything happens in your browser, so nothing is uploaded and there is no size-based paywall.

  • Your files stay on your device

    Merge PDF runs in your browser, so nothing is uploaded — not the file, not even its name.

  • Free, with no sign-up

    No account, no watermark on your files and no daily limit for normal use.

  • Up to 50 files at once

    Each file can be up to 100 MB. Large or scanned files simply take a little longer.

  • Works on every device

    Windows, Mac, Linux, iPhone, iPad and Android, in any modern browser. Nothing to install.
