Frequently asked questions
Is there a file size limit?
There is no artificial limit. Because processing happens on your device, very large files simply depend on your device's memory — most phones handle 50-100 MB comfortably.
Is this tool free to use?
Yes. Merge PDF is completely free with no sign-up, no watermarks, and no usage limits.
Are my files or data uploaded to a server?
No. Everything is processed locally in your browser using JavaScript. Your files and text never leave your device, which makes this one of the most private ways to get the job done.
Does it work on mobile?
Yes. The tool is fully responsive and works on Android, iPhone, tablets, and desktop browsers.
