MP4 to MP3 on Windows: the sound from any video
Audio Converter takes the soundtrack out of a video and saves it as MP3, M4A, WAV or FLAC, on your PC. Type “mp4 to mp3” in Toolyn's search and it opens with the format already set. Drop one video or a whole batch.

How it works
4 steps, start to finish.
Open it
Search “mp4 to mp3”, or open Audio Converter and its From video tab.

MP4, MOV, MKV, WebM, AVI, WMV, M4V, MPG, TS, 3GP and FLV.
Pick MP3 and a bitrate
128, 192, 256 or 320 kbps, and keep the sample rate or set 44.1, 48 or 96 kHz.

What it can do
MP4 to MP3, in detail.
Four formats out
MP3, M4A, WAV or FLAC.
Lossless when it can
“Copy when it fits” keeps the sound as it is when it's already in the right format, with no re-encoding.
High resolution kept
24-bit sound stays 24-bit in WAV and FLAC.
Trim too
The Trim tab cuts the start and end of a recording.
Audio files as well
Convert MP3, WAV, FLAC, M4A and other audio files between formats.
Uses FFmpeg, a free helper Toolyn installs for you with one click through WinGet (about a 100 MB download, for your Windows account only). If FFmpeg is already on your PC, Toolyn finds it.
Questions
MP4 to MP3: plain answers.
Is my video uploaded?
No. The sound is extracted on your PC by FFmpeg. The only download is FFmpeg itself, once.
Can I convert several videos at once?
Yes. Drop as many as you like and they're converted one after another.
Which bitrate should I pick?
192 kbps is plenty for speech and most music. Pick 320 kbps if you want the best MP3 there is, or FLAC to lose nothing.
Can I cut out just part of the sound?
Use the Trim tab of the same tool to cut the start and the end, or Audio Studio for anything more.
