A single-purpose converter: MP4 or WAV in, MP3 or WAV out. It exists for the two conversions that come up constantly in game work — pulling the audio out of an MP4, and turning a large WAV into a shippable MP3.
The conversion runs in the page using the browser's own audio decoding, so a file never leaves your machine. That matters when the audio is unreleased, licensed, or simply not yours to upload.
How to use it
Drop in an MP4 or WAV file.
Choose MP3 or WAV as the output format.
If you picked MP3, choose the quality — higher bitrates for music, lower for short effects.
Convert, then download the result.
Convert another file without reloading the page.
Formats and options
Accepts MP4 (including video files, from which the audio track is taken) and WAV.
Outputs MP3 at a bitrate you choose, or WAV when you need it uncompressed.
No account, no upload, no queue — the file is decoded and re-encoded locally.
For trimming, normalising or batch work, use the Game Audio Processor instead.
