Frequently asked questions

Is this MP4 to MP3 converter really free?

Yes. It is completely free with no signup, no watermarks and no conversion limits.

Are my files uploaded to a server?

No. The converter uses WebAssembly to run FFmpeg inside your browser, so your MP4 file never leaves your device. That also means there is nothing for us to store or share.

Is there a file size limit?

There is no artificial limit. Because everything runs in your browser’s memory, very large files (over ~1.5 GB) may fail depending on your device.

Do I need to install any software?

No. Everything works in your browser, desktop or mobile. There is nothing to download or install.
