How to convert MP4 to MP3
- Drop one or more video files (MP4, MOV, WebM, AVI, MKV) into the upload zone above.
- Choose output quality: 128 kbps for everyday listening, 320 kbps for archival quality.
- Optionally set a time range to extract just a clip — enter start and end as HH:MM:SS.
- Add ID3 tags — title is prefilled from the filename, and you can set artist, album, and year globally.
- Click Extract audio → MP3 and download each file when it finishes.
Why use this tool?
- No file size limit — the encoder runs inside your browser using FFmpeg WebAssembly, so there is no server upload limit.
- Time range extraction — clip out just the section you need without a separate trim step.
- ID3 tag editor — set title, artist, album, and year so the audio file is properly labelled in your media player.
- Batch processing — add multiple files and extract them all in one click.
- 100% private — your video files never leave your device.
