fre:ac is a free, open-source audio conversion and CD ripping tool for macOS that handles virtually every audio format you're likely to encounter — converting between MP3, AAC, FLAC, Opus, Ogg Vorbis, WAV, and dozens more with full metadata preservation.
What is fre:ac?
fre:ac (short for free audio converter) is a cross-platform audio utility that combines a high-quality audio format converter with a full-featured CD ripper into a single, lightweight application. It's built on the BonkEnc engine and has been actively developed for over two decades, making it one of the most battle-tested free tools in this space.
Where other converters strip your carefully tagged library of its metadata, fre:ac treats tags as first-class citizens — artist, album, genre, cover art, and even ReplayGain values survive intact across every conversion. For anyone migrating a music library from FLAC to AAC (or vice versa), that alone is worth the download.
What does fre:ac do best?
fre:ac excels at batch conversion of large music libraries with lossless accuracy and zero metadata loss. Drop a folder of 2,000 FLAC files onto it, select your output codec and quality target, and walk away — the converter queues everything, uses all available CPU cores in parallel, and deposits clean, properly tagged files when it's done.
CD ripping is equally solid. fre:ac integrates with the freedb and MusicBrainz databases, so it automatically pulls track titles, artists, and album art the moment you insert a disc. The ripping quality is excellent — it uses Paranoia-style error correction under the hood, so scratched discs that defeat other rippers often yield clean results here.
- Format breadth: converts between MP3, AAC/M4A, FLAC, ALAC, Opus, Vorbis, WMA, WAV, AIFF, and many more
- Parallel encoding: saturates all CPU cores for dramatically faster batch jobs than single-threaded tools
- MusicBrainz integration: automatic CD metadata lookup with cover art
- ReplayGain support: calculates and embeds volume normalization tags per track and per album
- Playlist output: can write M3U/PLS playlists alongside converted files, preserving your library structure
Is fre:ac free?
Yes — fre:ac is completely free to download and use, with no feature limits, no nag screens, and no subscription tier. It's open-source software released under the GNU General Public License, so the full source is available on GitHub if you want to inspect or build it yourself.
There are no paid add-ons. Every codec and every feature is included out of the box.
Who should use fre:ac?
fre:ac is the right pick for anyone with a serious music library to manage. If you're digitizing a CD collection, converting FLAC rips to AAC for an iPhone, or reformatting a folder of podcast recordings for a client, fre:ac handles each scenario without fuss. Audiophiles appreciate the lossless-to-lossless paths and proper ReplayGain; casual users appreciate that it's free and doesn't nag them.
It's less suited to users who need advanced audio editing (EQ, trimming, noise reduction) — for that, Audacity or Fission is a better fit. And if you work exclusively in Apple's ecosystem and only ever touch ALAC or AAC, the built-in Music app handles basic conversions passably. But the moment your needs grow beyond that, fre:ac is where I'd send you.
What are the best fre:ac alternatives?
The closest free alternative is HandBrake for video — but for audio specifically, the field is sparse. XLD (X Lossless Decoder) is the Mac power-user favourite: tighter macOS integration, an excellent UI, and arguably better error-correction on damaged CDs. It's donationware. dBpoweramp is the gold standard for CD ripping accuracy and library management, but it's paid. ffmpeg covers every format imaginable but requires terminal fluency — not a GUI app.
Where fre:ac wins over XLD is in raw batch-processing throughput and cross-platform consistency — useful if you share workflows across Mac and Windows machines. Where XLD wins is polish and macOS-native feel.
