About this tool

Combine multiple PDF files into a single document, in exactly the order you want. Files are merged locally in your browser, so nothing is uploaded to a server.

Putting several PDFs into one file is a routine task — assembling applications, reports, or scans. This tool loads your documents, lets you arrange them, and stitches them together using PDF.js entirely on your device.

Why use it

A fast, private way to combine PDFs with full control over order — no accounts, no uploads, and no cost.
