How it works
Drop an MP3 file onto the converter above, or tap to open your file browser. Works on phone, tablet, and desktop.
Your browser decodes the MP3 audio and re-encodes it to OGG format using the built-in audio engine. No server needed.
Click the download button and get your OGG file. Ready to use in games, apps, or any software that accepts OGG audio.
All OGG tools
MP3 is the most widely played audio format in the world, but there are specific situations where OGG works better. Game developers reach for OGG because the format is open-source, patent-free, and decodes efficiently on low-power hardware. Engines like Godot, Unity, and RPG Maker either prefer or require OGG for streaming audio assets. If you have MP3 files you want to use in a project like that, converting them is the straightforward solution.
Linux users sometimes prefer OGG as well. It fits naturally into the open-source ecosystem, and tools like VLC, Rhythmbox, and Audacity handle it natively. For general listening, MP3 or AAC makes more sense. For software compatibility in specific environments, OGG is the right call.
The OGG file produced by this converter uses the Opus codec, which is the modern standard for OGG audio. Opus is technically superior to the older OGG Vorbis codec: it handles a wider range of bitrates, performs better at low bitrates, and has lower latency. Most software that reads OGG files supports Opus. If you specifically need OGG Vorbis for a legacy tool that does not support Opus, check your tool's documentation before converting.
Both MP3 and OGG are lossy formats. Converting from one to the other involves a second round of lossy compression, which means some additional quality loss is unavoidable. The result will sound very close to the original MP3 in normal listening conditions, but it will not be bit-for-bit identical to what you would get by encoding from a lossless source like WAV or FLAC.
If you have the original recording in a lossless format, encode directly to OGG from that source instead. It will always produce a better result than transcoding through MP3.
