About the Merge PDF

Merge PDF combines two or more PDF files into a single document. Add your files, drag them into the order you want, and download one tidy PDF.

Everything happens in your browser using the PDF itself, so your documents are never uploaded to a server, which makes it safe for contracts, statements and other private files.

There is no file-count limit, no watermark and no sign-up.
