Frequently asked questions
Will I lose video quality converting MP4 to MP3?
No — MP3 is audio-only, so only the soundtrack is kept. There's no video quality to preserve since the video track is dropped entirely.
What bitrate does the MP3 come out at?
The converter uses a standard high-quality MP3 bitrate suitable for music and speech; the exact setting depends on your server's configuration.
Can I convert a video I downloaded from another site?
Yes — any MP4 file works, whether it's your own recording or one you downloaded elsewhere. Only convert files you have the right to use.
Is there a file size limit?
The maximum upload size depends on your server's configuration and is shown above the drop zone once the page loads.
What happens to my file afterward?
It's deleted from the server the moment the converted MP3 reaches you — also on failure or cancellation. Only your browser keeps a copy.
