Frequently asked questions
Are my files uploaded to a server?
The merge runs entirely in your browser using JavaScript. Your files are never uploaded to a server, so nothing leaves your device and nothing is stored.
Do I need to sign up or pay?
No. There is no sign-up, no email address, and no watermark on the result. The tool is free with no usage limit.
How many PDFs can I merge at once?
There is no fixed limit. Because the merge happens in your browser, the practical ceiling is your device's memory — a few dozen ordinary documents is comfortable.
Is the quality reduced?
No. Pages are copied into the new document as they are, so text stays selectable and images keep their original resolution. Nothing is re-compressed.
