Merge PDF files

Join two or more PDF documents into a single file.

Drop the files in the order you want them and you get one document back, with every page of the first, then every page of the second, and so on. Page sizes can differ; the result simply keeps each page as it was.

This is the one tool on the site where people most often reach for an upload service without thinking — and PDFs are exactly the files most likely to be contracts, invoices, medical records or scanned identity documents. Here the documents are opened and joined by the page you are reading, and no copy of them is sent anywhere.
