Quick answer: To convert AU to WAV, add the AU file to the iHateFiles AU to WAV converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. AU is a format most software has stopped opening. WAV is not.
Should you convert AU to WAV?
A safe conversion: AU and WAV are both lossless, so this is a change of container rather than a change to the picture.
Nothing is discarded
AU and WAV are both lossless, so every pixel survives the move intact. Convert back and forth as often as you like; the image does not degrade.

What usually goes wrong
About the AU. Many AU files use 8-bit µ-law companding, which sounds like a telephone. That is how they were recorded, not a conversion fault.
About the WAV. Converting an MP3 to WAV makes the file ten times larger without recovering anything. The detail the MP3 discarded is gone.
How to convert AU to WAV
- Add your AU file. It is read from your disk and stays there.
- Check the settings. The output format is already set to WAV.
- Press convert and the WAV file is saved back to your device.
Questions
How do I convert AU to WAV?
Open this page, add your AU file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this AU to WAV converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to WAV lose quality?
WAV is lossless, so this step throws nothing away. If the original was already a lossy format, the damage it did cannot be undone, but nothing further is lost.
Can I convert several AU files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
