About the Free PDF Merge Tool

Combine multiple PDF files into a single document. Drop in two or more PDFs, drag to reorder, and export — all in your browser. No file is uploaded, which is unusual for a PDF merger (most cloud tools require an upload).

How to use it

  1. 1

    Upload PDFs

    Drop two or more PDF files into the upload area.

  2. 2

    Reorder

    Drag the file tiles to change the order. The final PDF concatenates in that order.

  3. 3

    Merge and download

    Click merge — the combined PDF saves to your device.

Frequently asked questions

Is there a file count limit?

Practically no, but merging dozens of large PDFs may slow your browser. Try in batches if you hit slowness.

Are my PDFs uploaded?

No. The merge happens entirely in your browser using PDF-Lib. Your files never leave your device.
