Free online VGM to FLAC converter

Some audio players and editing workflows accept FLAC but cannot open VGM files. Converting creates a playable audio rendering of the game music; it does not preserve the original chip-command data.

What the VGM format is

VGM (Video Game Music) stores sound-chip register commands and timing information, rather than recorded audio samples. Game music logging tools and emulators create VGM logs, which are commonly played with chiptune players or used to preserve music from older game systems.

What the FLAC format is

FLAC stores audio as losslessly compressed digital samples. It is useful for archiving or editing a rendered soundtrack when you want lossless audio and broad support in audio players and software. FLAC contains the waveform, not the VGM playback events or chip settings.

How to convert VGM to FLAC

Online on 101convert.com

1. Upload the VGM file to the converter on this page. You can add several files for batch conversion; the per-file size limit is shown on the page.
2. Before converting, set the sample rate and channel count if needed.
3. Convert the files, then download the resulting FLAC files. Conversion runs on the server with FFmpeg.

Offline with desktop software

On Windows, foobar2000 can render VGM through its Game Emu Player component and encode the result as FLAC.

1. Install foobar2000 and the Game Emu Player component (foo_gep), then open the VGM file in foobar2000.
2. Select the track, open Convert → Quick convert, choose FLAC as the output format, and start the conversion. If FLAC is not available, configure or install a FLAC encoder in foobar2000's converter settings.

Quality and limitations

The FLAC encoding can be lossless relative to the rendered samples, but the rendering depends on the chip emulation and selected sample rate and channels. Because VGM is event data rather than sampled audio, conversion necessarily produces a playback rendering; it cannot retain the original VGM commands in the FLAC file.
