About this tool
Turn MP3 files into OGG. The OGG output uses Opus audio. MP3 uses lossy compression. A higher bitrate makes a larger file but cannot restore detail already removed from the source. OGG output contains Opus audio, not Vorbis. Some players that accept OGG Vorbis do not accept OGG Opus, so test the destination player.
Convert audio to MP3, WAV, M4A, AAC, OGG, Opus or FLAC in your browser, with bitrate controls for lossy outputs. Change audio format, choose a bitrate for compressed outputs and convert several files at once. OGG inputs can contain Vorbis or Opus; OGG outputs use Opus.
Questions
Does MP3 to OGG improve audio quality?
MP3 uses lossy compression. A higher bitrate makes a larger file but cannot restore detail already removed from the source. OGG output contains Opus audio, not Vorbis. Some players that accept OGG Vorbis do not accept OGG Opus, so test the destination player. Conversion cannot improve source quality. Input decoding depends on your browser.
Which formats are supported?
MP3, WAV, M4A/AAC, OGG with Vorbis or Opus, Opus and FLAC can be read when your browser supports decoding their audio. Outputs are MP3, WAV, M4A/AAC, OGG with Opus, Opus and FLAC. Vorbis encoding is not available.
What bitrate should I choose?
128 kbps suits speech and smaller music files. 192 or 256 kbps keeps more detail. A higher bitrate makes a larger file and cannot restore detail already lost.
Does converting to WAV or FLAC improve quality?
No. They avoid another round of lossy compression, but cannot recover detail from an MP3 or other lossy source. WAV output uses 16-bit PCM.
Can I convert WMA, AMR or AIFF?
These formats are tried using your browser's audio decoder. If it cannot read them, this tool explains the limitation. WMA and AMR usually need a separate converter.
Are files uploaded?
No. Decoding and encoding happen in your browser tab. Large files need enough memory on your device.
