Merge PDF Files Online — Free, Unlimited, and 100% Private

Merging PDFs is one of the most common document tasks there is — combining scanned ID pages, invoices, or chapters into a single file — yet most free mergers upload your documents to a server and then throttle or watermark the result. This merger runs a full PDF engine inside your browser: your contracts, IDs, and financial documents never leave your device.

Add files, drag them into the exact order you need, and download the combined PDF. There are no page limits, no hourly task caps, no watermarks, and no account — and it keeps working offline once the page has loaded.

Frequently Asked Questions

Everything you need to know about using Merge PDF safely and efficiently.

No. The merge happens entirely inside your browser using a client-side PDF engine. You can verify this in your browser's network inspector — no document data is transmitted.
