How do I convert an AU file to PAF using LetsConvert?

Upload your .au file, select PAF as the output format, and click 'Convert'. You can adjust sample rate or bitrate before converting. Once finished, download the .paf file. Batch conversion is supported—just upload multiple AU files.

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

AU files from Sun/NeXT systems offer no metadata support and consume more space. PAF provides lossless compression, reducing file size by up to 50%, and is recognized by many modern audio editors and players. It also allows embedding of metadata like artist and title.

What technical data is preserved when converting AU to PAF?

The conversion preserves sample rate, bit depth, and channel count exactly. AU's u-law or linear PCM audio is repacked into PAF's lossless codec, so no audio data is lost. ID3 and RIFF metadata are mapped to PAF's tag system, ensuring information like timecode and title remain intact.

Is AU-TO-PAF free to use?

Yes, AU-TO-PAF on LetsConvert is 100% free with no registration or hidden fees required.
