Free online VGZ to MP3 converter

A VGZ file is a compressed video game music log, not a conventional audio recording, so many phones, editors, and players that accept MP3 cannot open it directly. Convert it when you need a widely supported audio file for playback, editing, or sharing.

What the VGZ format is

VGZ is a gzip-compressed VGM file. VGM files store sound-chip commands recorded from video game audio hardware; compatible playback software recreates the sound from those commands. You may encounter VGZ files in video game music archives or recordings made with emulators and VGM logging tools.

What the MP3 format is

MP3 stores audio as a compressed waveform. It is supported by most phones, computers, media players, and audio editors, making it useful when a player does not support game music formats. MP3 is lossy, so some audio information is discarded during encoding.

How to convert VGZ to MP3

Online on 101convert.com

1. Upload the VGZ file to the converter. You can add several files for batch conversion; the page shows the per-file size limit.
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 on its server.

Offline with desktop software

FFmpeg is a free, open-source command-line tool available for Windows, macOS, and Linux. The build must include the libgme decoder for VGM/VGZ and the libmp3lame MP3 encoder. Check that ffmpeg -decoders lists libgme; if it does, convert with:

ffmpeg -i input.vgz -t 180 -c:a libmp3lame -q:a 2 output.mp3

This example limits the output to 180 seconds and uses a variable-bitrate MP3 quality setting. Change input.vgz, output.mp3, and the duration to suit your files and desired track length.

Quality and playback limitations

VGZ contains sound-chip instructions rather than recorded audio, so conversion synthesizes the sound during playback; the result can depend on the decoder. Some game tracks loop or have no fixed end, so choose a duration when you need a particular playback length. A higher MP3 bitrate can reduce encoding loss, but cannot add detail absent from the synthesized source.
