How do I convert AU to OGA online?

Upload your AU file, choose OGA as the target format, optionally adjust bitrate (e.g., 192 kbps Vorbis or Opus), and click Convert. Download the resulting OGA file instantly after processing.

Why should I convert AU to OGA instead of keeping AU?

AU files are often uncompressed and used on legacy Sun/NeXT systems, resulting in large file sizes and poor browser support. OGA (Ogg container with Vorbis/Opus audio) offers superior compression—reducing file size by 70–80% while preserving audio fidelity—and is natively supported in most modern browsers, making it ideal for websites and portable devices.

What happens to audio quality when converting AU to OGA?

Sample rate and channel count are preserved, but audio is re-encoded with lossy Vorbis or Opus compression. Bitrate is adjustable (default 192 kbps) to balance size and quality; metadata may be retained. Exact sample-level fidelity is not kept—use FLAC in an Ogg container if you need lossless conversion.
