Why convert MP4 to MP3?
Extracting audio from video is one of the most common conversions. Whether you want to save a podcast that was recorded as video, extract music from a music video, or create an audio-only version of a lecture, MP4 to MP3 strips the video track and keeps just the audio. The resulting MP3 file is dramatically smaller and plays on any device.
Common use cases
- Extracting audio from screen recordings
- Saving podcast episodes as audio files
- Creating ringtones from video clips
- Listening to lecture recordings on audio-only devices

Tips for MP4 to MP3 conversion
- High quality (192kbps) is recommended for music. Medium (128kbps) works fine for speech and podcasts.
- The conversion only extracts the existing audio — it can't improve poor-quality audio from the original video.
- If the MP4 has multiple audio tracks (like different languages), the default track will be extracted.

Frequently asked questions
Does converting MP4 to MP3 lose quality?
There is some quality loss since MP3 uses lossy compression. However, at 192kbps (our High setting), the difference is imperceptible for most listeners. The audio in the original MP4 was already compressed with AAC, so you're re-encoding from one lossy format to another.
How long does MP4 to MP3 conversion take?
Usually 2-5 seconds for a typical music video or song. Longer videos (1+ hours) may take 15-30 seconds. The conversion speed depends on the file size, not the video length.
Can I convert a YouTube video to MP3?
ConvertThis converts files you upload — it doesn't download from URLs. You'll need to save the video file first, then upload it here for conversion.
