OGG to MP3 Converter Convert OGG Vorbis audio files to MP3 format in your browser.

The tool reads the OGG file and decodes it using AudioContext.decodeAudioData(), which leverages the browser's built-in OGG Vorbis decoder. The resulting AudioBuffer contains raw PCM samples. For MP3-compatible output, the tool uses a MediaRecorder-based pipeline: the PCM audio is played through an OfflineAudioContext connected to a MediaStream destination, and the stream is recorded using MediaRecorder with a compatible audio MIME type. The recorded chunks are assembled into a downloadable audio file. The conversion preserves the original audio's sample rate and channel configuration. For browsers with AudioEncoder support, a more direct encoding path may be used for better quality control.
