Merge PDF

Drop multiple PDFs, reorder them, and save a single combined file. No uploads, no accounts, no watermarks.

Updated April 2026

What it does

A free PDF merger that runs entirely in your browser. Drop multiple PDFs, reorder them, and download a single combined file. No upload limit beyond what your device can hold in memory; no watermarks, no account, no wait.

Most online PDF mergers upload your files to a server. That’s fine for a public doc, but risky for bank statements, contracts, or medical records. This tool uses the browser-native pdf-lib library — the merge happens entirely on your machine.

How to use it

  1. Drop two or more PDFs.
  2. Use ↑ ↓ to put them in the right order.
  3. Click Merge.
  4. Download the combined PDF with one click.
