What are the steps to convert an AU file to OGG with LetsConvert?

Upload your AU file to LetsConvert, select OGG as the output format, adjust the Vorbis quality slider if needed, and click Convert. You can upload multiple AU files for batch processing. Once conversion finishes, download the OGG files to your device. The process is entirely in-browser and requires no software installation.

Why should I convert AU to OGG instead of keeping the original?

AU files are often large and primarily used on legacy Unix systems. Converting to OGG Vorbis gives you compressed audio that's much smaller for storage and transfer, while retaining excellent audio quality for everyday listening, web pages, and podcasts. OGG is also supported by all modern browsers and most media players, so it's a practical format for publishing or archiving.

What happens to sample rate and audio metadata during AU to OGG conversion?

When converting, LetsConvert preserves the source sample rate, bit depth, and channel configuration as the basis for OGG encoding. Metadata tags (artist, title, album) are carried over. Since OGG is lossy, the exact PCM samples aren't retained, but at high bitrates (e.g., 320 kbps) the resulting audio is perceptually equivalent for most listeners. You can also change the bitrate to trade off file size and quality.

Yes! AU-TO-OGG works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?
