OGG Vorbis is an open-source MP3 alternative. Quality is slightly better than MP3 at the same bitrate and it's patent-free — popular in games, Spotify, and Wikipedia. However, OGG isn't always ideal — especially when you need MP3.
MP3 brings the advantage: Most compatible audio — plays on every phone, car, speaker. Small, daily-use quality.
With FORMATTO, you can convert OGG to MP3 in seconds. Everything runs 100% on your device — files are never uploaded to any server, so your privacy is guaranteed. Did you know? Spotify streaming uses OGG Vorbis 96-320 kbps under the hood.
