    About this tool

    Need to submit several scans as a single document? This tool merges any number of PDF files into one, in the order you choose — and unlike most online PDF sites, your documents are never uploaded. The merging happens entirely on your device using an open-source PDF engine running in your browser.

    That privacy matters: certificates, contracts, bank statements and ID scans are exactly the documents people merge most, and exactly the ones you should not hand to a random server. Here they stay on your machine, and the merge is instant because nothing travels over the network.

    Add files, drag them into order with the arrow buttons, remove any you added by mistake, and click Merge — the combined PDF downloads immediately with every page at its original quality.

    How to use

    1. Choose two or more PDF files.
    2. Reorder them with the ↑ ↓ buttons — the list order is the final page order.
    3. Click Merge PDFs.
    4. The combined file downloads as merged.pdf.

    Yes — use the ↑ and ↓ buttons on each file. The final PDF follows the list order top to bottom.

    No. Pages are copied into the new file as-is — text, images and formatting are preserved exactly.
