About this tool
Merging PDFs means combining several documents into one, in the order you choose: both sides of an ID card, the receipts for an invoice, the annexes of a proposal. Here it happens in your browser's memory: the files do not travel to any server.
Pages are copied as they are, without recompressing them: text stays selectable and images keep their quality. The result is a new document, so it does not inherit the originals' title or author.
The practical limit is your device's memory: merging dozens of PDFs with hundreds of pages on a phone can be slow. If the result is too heavy for a portal, run it through Compress PDF afterwards.
