Why use Merge PDF?

Combining PDFs is a common task — 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

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

Tips & best practices

Files are processed in the order you add them — re-add to change order.
There is no file size limit other than what your browser can hold in memory (typically a few hundred MB).
Encrypted PDFs must be unlocked first using our PDF Password Remover.
