Free online VGM to MP3 converter

Some phones, audio editors, and sharing platforms do not accept VGM files, which store game sound-chip instructions rather than ordinary audio. Converting one to MP3 renders those instructions as playable audio in a widely supported, smaller file.

What the VGM format is

VGM (Video Game Music) records timed writes to sound chips used in game consoles and arcade machines. Emulators and game-audio logging or ripping tools create VGM files; you may encounter them in collections of game soundtracks. A VGM player or converter must emulate the recorded chips to produce audio.

What the MP3 format is

MP3 is a lossy audio format supported by most media players, phones, and editing programs. It is useful for sharing and portable playback, and is generally much smaller than uncompressed audio; unlike VGM, it contains rendered sound rather than chip instructions.

How to convert VGM to MP3

Online on 101convert.com

1. Upload the VGM file on the converter page. You can add several files for batch conversion; the per-file size limit is shown on the page.
2. Before converting, set the bitrate, sample rate, and channel count if needed.
3. Start the conversion, then download the MP3 file or files. The page's converter uses FFmpeg.

Offline with desktop software

On Windows, use the free VGMPlay package's vgm2wav utility to render the file to WAV, then encode the WAV with FFmpeg. For example, run vgm2wav input.vgm output.wav, followed by ffmpeg -i output.wav -c:a libmp3lame -b:a 192k output.mp3. Change 192k to choose a different MP3 bitrate. VGMPlay's rendering utility and FFmpeg are separate steps; FFmpeg encodes the rendered audio, not the VGM chip data directly.

Quality and compatibility

VGM playback depends on chip emulation, so the rendered sound can vary with the player or emulator. MP3 encoding is lossy; keep the original VGM or an uncompressed WAV if you need the source data or a lossless audio master. The chosen sample rate and channel count affect the rendered MP3, while bitrate controls its size and compression quality.
