WMV to AU Converter

Convert WMV files to AU. Free, without uploading.

This tool converts WMV files to AU. WMV is Microsoft’s Windows Media video format, used by older Windows software and older PowerPoint versions.

Sun/NeXT audio. Only the audio of the WMV video is kept and saved as AU; the picture is dropped. AU is lossless, so the audio keeps the quality it has in the WMV file.

Conversion runs on your device; your file is never sent to a server. The components download once on first use, and later conversions start right away.

How to use

1. Choose the WMV video, drag it in, or paste its link.
2. Choose the audio quality; optionally enter a start and end time.
3. Press "Convert" and download the AU file.
