About Merge PDF
Merge PDF combines two or more PDF files into a single document — right inside your browser. Add your files, drag them into the order you want, and download one merged PDF in seconds.
Because everything runs locally on your device, your files are never uploaded to a server. It's free, unlimited, and works in any modern browser on desktop or mobile.
