fre:ac is a free audio converter and CD ripper with support for various popular formats and encoders. It currently converts between MP3, MP4/M4A, WMA, Ogg Vorbis, FLAC, AAC, WAV and Bonk formats.

With fre:ac you easily rip your audio CDs to MP3 or WMA files for use with your hardware player or convert files that do not play with other audio software. You can even convert whole music libraries retaining the folder and filename structure.

The integrated CD ripper supports the CDDB/freedb online CD database. It will automatically query song information and write it to ID3v2 or other title information tags.

    fre:ac can be installed on a USB stick or external drive so you can take it with you and use it on any computer. It will also store its configuration files on the portable drive. That way it will always start up with your custom settings.

  • Multi-core optimized encoders to speed up conversions on modern PCs

    The MP3, MP4/M4A, Ogg Vorbis, FLAC, AAC and Bonk encoders integrated with fre:ac make use of modern multi-core CPUs, so ripping and converting speeds get a real boost. You will save time and get the job done quickly.

    fre:ac's user interface is designed to be intuitive so you will be able to use the basic features without any trouble. It still offers advanced options when you need them so you will be able to go beyond simple ripping and format conversion using fre:ac.
