Convert your audio or video files to the open and patent-free OGG Vorbis format using our free online converter. OGG Vorbis is a lossy audio format known for its good quality and efficiency, often used for web streaming and in games. Convert from MP3, WAV, FLAC, AAC, M4A, video, and more. Our service is fast, free, private (files deleted within about an hour), and requires no registration. Our converter encodes Vorbis at VBR quality 5, which averages about 160 kbps.
Creating OGG Vorbis files is simple:
OGG from the 'Convert to:' dropdown menu.
OGG is a free, open container format maintained by the Xiph.Org Foundation. While the OGG container can hold various streams (audio, video, text), when people refer to an "OGG file" for audio, they almost always mean audio compressed with the Vorbis codec, stored inside an OGG container (resulting in .ogg files).
Vorbis is a lossy audio compression method designed to compete with MP3 and AAC. It aims to provide higher fidelity than MP3 at similar bitrates and is completely free from patents, making it attractive for open-source projects and web distribution. OGG Vorbis is commonly used by Spotify for streaming (though they use other formats too) and in many video games.
OGG Vorbis files are well-supported by many software applications:
Most modern desktop systems and Android devices can play OGG Vorbis files without issues.
| Full name | Ogg Vorbis |
|---|---|
| Compression | Lossy |
| Developed by | Xiph.Org Foundation |
| Introduced | 2002 |
| File extension | .ogg |
| Typically used for | Games, open-source software, web audio |
| Plays on | Android, Chrome, Firefox, Edge, VLC, game engines; limited on Apple devices |
| Our output | Vorbis, VBR quality 5 (about 160 kbps) |
We encode OGG files with the Vorbis codec at variable bitrate quality 5, which averages around 160 kbps. Because it is VBR, the bitrate rises for complex passages and drops for simple ones. The sample rate and channels are kept from your source. There is no quality slider, so every OGG uses this setting.
Our OGG files average about 1.2 MB per minute, a little smaller than our 192 kbps MP3s at about 1.44 MB. Vorbis at quality 5 sounds very good for music and speech. The main trade-off is compatibility: MP3 plays almost everywhere, while OGG is best supported in software, Android and web browsers.
Built-in support on iPhone and iPad has historically been limited, and Apple's Music app doesn't import OGG files. Depending on your iOS version you may need a third-party player such as VLC. If the audio is mainly for Apple devices, M4A or MP3 is the more reliable choice.
No. Ogg is a container that can hold Vorbis, Opus, FLAC and other streams. Most .ogg music files use Vorbis, and that is what our OGG output contains. If you want Opus audio instead, pick the Opus output, which uses the same Ogg container with a .opus extension.
Vorbis is open and royalty-free, so it can be used in any software without licensing fees. Game engines such as Unity and Godot import Ogg Vorbis for music and sound effects, many Linux distributions play it out of the box, and Chrome and Firefox support it for web audio.
Probably not. Our OGG output averages about 160 kbps, so a 128 kbps MP3 will usually get slightly bigger, and re-encoding one lossy format into another adds a small amount of extra loss. Converting to OGG makes most sense from lossless sources like WAV or FLAC, or when a program requires Ogg Vorbis.
