Free online VGM to OGG converter

Many music players and editors cannot open VGM logs, so converting one to OGG makes its rendered game audio easier to play and share. The conversion synthesizes the chip commands into audio; it does not preserve them as editable sound-chip data.

What the VGM format is

VGM (Video Game Music) stores timed commands for sound chips used in video game hardware, rather than a recording of the music. VGM files are commonly made by game-music logging or extraction tools and played with software that emulates the chips. Compressed versions often use the .vgz extension.

What the OGG format is

OGG is a multimedia container; music files with the .ogg extension commonly contain lossy Vorbis audio. Ogg Vorbis is supported by many media players and is useful for sharing or storing rendered music at a smaller size than uncompressed audio. Unlike VGM, it contains audio samples, not the original chip commands.

How to convert VGM to OGG

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 OGG file or files.

The page runs the conversion on its server with FFmpeg.

Offline with desktop software

On Windows, use foobar2000 with a VGM input component such as foo_input_vgm, plus the Converter component and an Ogg Vorbis encoder. Install the components, open the VGM file in foobar2000, select it in the playlist, then choose Convert → .... Select Ogg Vorbis as the output format, set the encoder quality, choose a destination, and start the conversion. If Ogg Vorbis is not listed, install or configure an encoder such as oggenc.

Quality and limitations

VGM playback is synthesized by an emulator, so the rendered sound can vary with the chip-emulation software and its settings. Ogg Vorbis encoding is lossy; retain the VGM if you need the original chip commands or want to render it again with different emulation settings.
