Yes. Merge PDF is completely free, with no sign-up, no watermark and no daily limits.

Are my files uploaded when I use Merge PDF?

No. Merge PDF runs entirely in your browser. Your files are processed on your device and are never sent to a server, so we can't see or keep them.

Does Merge PDF work on my phone?

Yes. It works in modern browsers on Android, iPhone, iPad, Windows, Mac and Linux — no app to install.

Does it work offline?

Yes. After the page has loaded once, the tool keeps working even if you turn off your internet connection.

Is there a file size limit?

There's no fixed limit. Because processing happens on your device, the practical limit is your device's memory — most handle large files comfortably.
