Sample output — your files never leave your device.
Add all your PDFs, then arrange them in the order you want using the controls — the merged document's pages follow that sequence exactly.
No. Pages are copied directly into the new document rather than re-rendered, so text stays selectable and images keep their original quality.
No server-imposed limits — the practical ceiling is your device's memory, since merging happens locally. Everyday documents merge instantly.
No — that's the point of this tool. Most online mergers upload your files to a server; this one assembles the PDF entirely in your browser, so confidential documents never leave your device.

GenRise Merge PDF combines multiple PDF files into one document, in the exact order you arrange them. It's built with pdf-lib running in your browser — pages are copied directly into a new document, so there's no re-rendered quality loss and, more importantly, your documents are never uploaded to a server. That makes it safe for the merges that matter most: application packets, contracts, bank statements and anything confidential.
Merge PDF runs entirely in your browser. Anything you enter or upload is processed locally and never sent to a server. There is no account required, no tracking of your content, and no data collection.
