Questions
Does MP4 to MP3 upload videos?
No. The MP4 is processed locally in your browser after the converter engine loads, and only your chosen MP3, WAV, or FLAC output is downloaded by you.
Does this keep the video track?
No. MP3, WAV, and FLAC exports extract audio only and drop the video stream.
Can I convert other formats here too?
Yes. This page is optimized for MP4 to MP3, but the shared converter also accepts common audio input and can export MP3, WAV, or FLAC when supported.
Does Utilumo upload my input?
No. This tool is designed for local browser processing and does not send your input to a server.
Do I need an account?
No. Utilumo tools are built to work without accounts or sign-in.
