It accepts .ogg, .opus and .oga files and converts them to MP3 at 128, 192, 256 or 320 kbps.
OGG and Opus show up in game audio, Discord voice messages, and stream rips, but many editors, phones, and players only handle MP3. Here is how to convert:
OGG usually refers to Vorbis audio in an .ogg container - an open, free codec that was popular in games and streaming before wider MP3 licensing. Opus is a newer open codec, often stored in .opus or .oga files, and it is more efficient than both Vorbis and MP3 at low bitrates - which is why Discord and many VoIP apps use it. Both are lossy, and both convert to MP3 the same way through this tool.
Discord voice messages save as OGG/Opus, and plenty of game engines bundle sound effects and dialogue the same way. If you need to edit that audio in a tool that only reads MP3, or share it with someone whose player does not support Opus, convert it here in a few seconds.
OGG and Opus are already lossy formats, so converting to MP3 is a lossy-to-lossy conversion - some additional audio data is discarded during the MP3 encode. At 320 kbps that extra loss is close to inaudible for most listeners. If fidelity matters most, keep the original OGG or Opus file and only convert copies you plan to share elsewhere.
The bitrate controls how much audio data the MP3 keeps per second. A practical breakdown:
Drop in a batch of OGG and Opus files together, set the bitrate once, and convert them all in parallel. When they finish, download the entire batch as a single ZIP instead of saving each one by hand.
Note: OGG and Opus input may not decode in Safari - Safari does not support those codecs natively. Use Chrome or Firefox for this tool.
SoundCloud accepts and recommends lossless uploads - it re-compresses everything for streaming, so starting from the best source you have gives the best result. If your only copy is an OGG or Opus file, convert it to MP3 for sharing demos and DMs, but keep the original for anything you plan to upload for release.

OGG (Vorbis) and Opus are both open audio codecs, often packaged in an .ogg or .oga container. Opus is newer and more efficient at low bitrates. This tool accepts both and converts either to MP3.
OGG and Opus are already lossy formats, so converting to MP3 is a lossy-to-lossy conversion. At 320 kbps the extra loss is close to inaudible for most listeners.
No. Conversion happens entirely in your browser using the Web Audio API and a local MP3 encoder. Your files never leave your device.
Discord voice messages and many game engines use OGG or Opus for compact audio. Convert them to MP3 to edit, share, or play them in apps and devices that only support MP3.
OGG and Opus input may not decode in Safari - Safari does not support those codecs natively. Use Chrome or Firefox to convert OGG or Opus files.
Yes. Add as many files as you want, mix OGG and Opus freely, convert them all in parallel, and download everything as one ZIP.
100 MB per file. There is no limit on the number of files you can convert.
Converting from M4A or FLAC instead? Try the M4A to MP3 converter or FLAC to MP3 converter. The full audio converter handles WAV, MP3, M4A, FLAC, AAC and Opus in one place. Already have an MP3 that is too big? Use the MP3 compressor. Cut and trim with the MP3 cutter, or add smooth fades with the audio fade tool. Working from WAV? Use the WAV to MP3 converter.
