Frequently asked questions
- Does this extract only the audio from the video?
- Yes. The video track is discarded and only the soundtrack is saved as an MP3, so the download is far smaller than the video and plays in any audio app — handy for turning a talk, interview or music video into something you can listen to with the screen off.
- Which video formats can I use to extract audio?
- Any format the converter accepts — MP4, MOV, AVI, MKV, WMV, FLV, WebM. Just upload the video and choose MP3 as output; the audio is pulled straight out of the file, so there is nothing to re-record or download twice.
- Can I extract audio from several MP4 videos at once?
- Yes. Add all your MP4 files together and click Convert — each one's audio is extracted as a separate MP3, so a whole folder of clips becomes a set of MP3s in one pass.
- Will the audio quality drop when I extract MP3 from MP4?
- The audio inside an MP4 is usually AAC, and saving it as MP3 re-encodes it, so there is a small one-time quality step. At the default bitrate it is inaudible for speech and fine for music — most extracted MP3s land around 128–192 kbps, which matches typical streaming quality. The MP3 can never sound better than the track already in the video, only more compatible.
- Is there a size or length limit for the video?
- You can upload files up to 2 GB, which is several hours of audio, so full lectures, interviews, sermons and long recordings convert to a single MP3 without being trimmed or split.
- Can I do this on my phone and use the MP3 as a podcast or ringtone?
- Yes. Open Converters.live in any mobile browser, upload the MP4 and download the MP3 — no app to install. The result is a standard MP3 that plays in podcast apps, music players and car stereos; for a ringtone, upload a short clip, since most phones cap ringtones at 30–40 seconds.
About MP4 and MP3
Key things to know before you convert MP4 to MP3:
MP4
MP4 with H.264 is the universal video format: phones, TVs, browsers, editors and messengers all play it. When in doubt, send MP4.
MP3
MP3 is the most compatible audio format in existence: every player of the last 25 years handles it. Less efficient than modern codecs, but compatibility usually wins.
