Audio to OGG Converter
Convert MP3, WAV, M4A or FLAC files to OGG Vorbis for web games, streaming and open-format needs. Free, no signup, in your browser.
Everything runs inside your browser — your file is never uploaded to a server.
First run downloads the media engine (~30 MB) once, then it stays cached.
About this tool
This converter re-encodes MP3, WAV, M4A or FLAC audio into OGG Vorbis, an open, royalty-free codec favored by web games, Linux apps and open-source projects. OGG often achieves smaller file sizes than MP3 at comparable perceived quality, making it a good fit for embedding sound effects and music in browser-based games or streaming setups that prefer patent-free formats. You set a quality level, the FFmpeg-powered engine handles decoding your source and encoding to Vorbis, and everything happens locally in your browser tab. This means large sound libraries or licensed music you don't want on a third-party server stay entirely on your machine. The first run downloads the FFmpeg core once; afterward, converting more files is fast and works offline from cache.

Why use this tool
OGG Vorbis is the go-to open-format codec for game engines, Linux software and projects that want to avoid patent-encumbered formats. Converting here lets you produce compatible OGG assets without desktop tools or uploading proprietary or licensed audio to an external service.
Tips & best practices
- Use quality 6 or higher for music you want to sound close to the original source.
- Lower quality settings (2-3) are fine for short game sound effects where size matters more than fidelity.
- Test playback in your target engine or browser, since OGG support can vary slightly across platforms.
Common use cases
- Preparing sound effects and music for an HTML5 or Godot web game.
- Converting licensed MP3 tracks to OGG for open-source project compliance.
- Creating smaller audio assets for a Linux application.
- Encoding podcast episodes to OGG for open-format distribution.
- Converting FLAC music archives to OGG for space-saving streaming.
Frequently asked questions
Is OGG better quality than MP3?
At similar file sizes, OGG Vorbis often sounds slightly cleaner than MP3, especially at lower bitrates, though both are lossy formats.
What quality setting should I pick?
Quality level 5-6 (roughly 160-192kbps equivalent) works well for music, while lower settings suit spoken word or game sound effects.
Is there a limit on file size?
No hard limit, but conversion speed depends on your device, so files up to a few hundred megabytes work best.
Can I convert audio to OGG on my phone?
Yes, this works in modern mobile browsers, though larger files take longer on phone hardware.
Are my files sent anywhere during conversion?
No, conversion happens locally using WebAssembly FFmpeg, so your audio never leaves your device.
