    Why use Merge PDF?

    Combining PDFs is a common task β€” emailing a complete report, stitching scanned receipts together, or assembling a portfolio. Most online mergers upload your files to a server, which is slow and risky for sensitive documents. Our merger runs entirely in your browser, so nothing ever leaves your device.

    How it works

    1. Add your files β€” Drag and drop or pick PDFs from your computer.
    2. Reorder if needed β€” Remove any file you don't want with one click.
    3. Click Merge β€” A single combined PDF is built locally and downloaded instantly.
