OGG (Vorbis) is an open, royalty-free audio format that compresses smaller than MP3 at the same quality. It is widely used in games (Godot, Unity), on Spotify and in open-source software. This free tool converts MP3, WAV, M4A, FLAC, OPUS and more to OGG in your browser.

Open, efficient and great for games

Vorbis has no licensing fees and is the standard audio format for many game engines, where small file size and free use matter. Converting to OGG keeps your sound effects and music light and fully open, ready to drop into a project.

Conversion happens entirely on your device with WebAssembly — nothing is uploaded. No sign-up, no watermark and no file limit, and you can set the quality to balance OGG size against fidelity.
