Choose PDF files or drag & drop them here

Files are processed on your device — nothing is uploaded.

    How to use the Merge PDF

    1. Click “Choose PDF files” or drag and drop your PDFs.
    2. Use the arrows to put the files in the right order.
    3. Click “Merge PDF” and download the combined document.

    Private by design

    Unlike most online PDF tools, merging happens on your own device using JavaScript. Your documents are never sent to a server, which makes this tool safe for contracts, bank statements and other sensitive files.

    Tips

    • Password-protected PDFs must be unlocked before they can be merged.
    • Very large files depend on your device memory; merging a few hundred pages is normally fine.

    Frequently asked questions

    Is there a limit on the number of files?

    There is no fixed limit. The practical limit depends on your device’s memory.

    Will merging reduce quality?

    No. Pages are copied as-is, so text, images and links keep their original quality.
