About MP4 to MP3
Extract the audio track from an MP4 video as a stand-alone MP3. The tool just demuxes when the source is already AAC; otherwise it transcodes to 192 kbps MP3.
Frequently asked questions
Why is the audio quality lower than the MP4?
MP3 at 192 kbps is good enough for speech and most music. If you need higher quality, save as M4A which keeps the original AAC stream losslessly.
Can I extract from a YouTube link?
No, upload the file directly. We don't fetch from third-party platforms.
