AlphaMomin

Free tool - private by design

Merge PDF files, free.

Combine several PDFs into one clean document. It all happens inside your browser, so your files never touch our servers.

Your files never leave your device. This tool runs entirely in your browser: nothing is uploaded, nothing is stored, nothing is logged. We are a security company, and we built it that way on purpose.

Merge your PDF files

    Add two or more PDF files to begin.

    How it works

    Three steps, nothing uploaded.

    1. Add your files

      Drop in the PDFs you want to combine, or choose them from your device. They load straight into this page, not to any server.

    2. Put them in order

      Reorder or remove files until the sequence is right. The page count for each file is shown so you can check as you go.

    3. Merge and download

      One click combines them, losslessly, and the finished PDF downloads to your device. We never see any of it.

    Good to know

    Questions people ask.

    Are my files uploaded anywhere?

    No. The merge happens entirely inside your browser using local code. Your PDFs never leave your device, are never sent to us, and are never stored. Close the tab and nothing remains.

    Does merging reduce quality?

    No. Pages are copied exactly as they are into the combined file, so text stays selectable and images keep their resolution. Merging is lossless.

    Is there a limit?

    You can combine up to 30 files at once. Because everything runs on your own device, very large files depend on your device memory rather than a server limit.

    What if a file is password protected?

    A password-protected PDF cannot be merged until its protection is removed. The tool will tell you clearly which file it could not read rather than produce a broken result.

    Does it work on a phone?

    Yes. It works in any modern mobile or desktop browser, with no app to install.

    Is it free?

    Yes, free with no account and no watermark. We build these tools because privacy-respecting software is the kind of work we do for clients every day.
