Extract MP3 audio from MP4 video.
This tool pulls the audio track out of an MP4 video and saves it as an MP3 file, dropping the video entirely. It's a common way to turn a recorded talk, podcast video, or music video into an audio-only file. Your file uploads over an encrypted connection and converts, usually in seconds. Files up to 100MB are supported.

Upload your MP4 file: drag it into the drop zone or click to browse. Files up to 100MB work.
Click Convert. The audio is extracted, usually finishing in seconds.
Download the MP3 file to listen to it, share it, or import it elsewhere.
The audio is re-encoded to MP3, a compressed format, so there's some quality loss versus the original track. For spoken word, podcasts, and most music this isn't noticeable at normal listening volumes, though audiophile-grade sources may sound slightly less crisp.
No. This conversion keeps audio only and discards the video permanently. Keep your original MP4 if you might need the video later; this tool doesn't modify or delete your source file, only the copy you upload.
