File size: OGG Vorbis at equivalent quality settings is typically 10–15% smaller than MP3.

Quality: This is a lossy-to-lossy transcode. Starting from MP3 introduces a second generation of compression. For best OGG quality, upload WAV or FLAC instead.

help FAQ

What is OGG Vorbis?

OGG Vorbis is a free, open-source, patent-free audio compression format. It achieves similar or better quality than MP3 at the same bitrate, without licensing fees.

Which platforms support OGG?

OGG is natively supported in Chrome, Firefox, Unity, Godot, Unreal Engine, VLC, and all major Linux media players. Safari and older iOS have limited support.

Is the conversion lossless?

No: this is a transcode from one lossy format (MP3) to another (OGG). A second generation of compression loss is introduced. For best quality, start from WAV or FLAC instead of MP3.

Why do game developers use OGG?

OGG Vorbis has no patent or licensing costs, making it ideal for indie and commercial games alike. Unity uses OGG for compressed audio by default.
