About this tool
Sometimes you only need the sound from a video: a recorded talk, a lesson, a voice message saved as video, or a song from a clip you filmed yourself. This converter takes the first audio track from your MP4, drops the picture and saves the sound as an MP3 that plays on any phone, car stereo or music player.
The conversion runs on our server with FFmpeg after you agree to the upload, because browsers cannot write MP3 files. Videos can be up to 50 MB and 15 minutes long, which suits phone clips and short recordings. Files are private and deleted within 30 minutes. Only convert videos you made or have permission to use.
