About this tool
The merge runs entirely in your browser with a PDF library, so documents such as contracts and invoices are not uploaded to any server. Pages keep their original size and content. Password-protected files cannot be read and need to be unlocked first.
Up to 50 files and 100 MB per file are supported, depending on your device's memory.
