How to convert FLAC to ALAC
FLAC (Free Lossless Audio Codec) and ALAC (Apple Lossless Audio Codec) are both lossless compression formats, meaning they preserve the exact audio data bit-for-bit. Converting between them is genuinely lossless: there is no quality loss of any kind because you are just repackaging the same audio data in a different container. FLAC is the standard for most open-source and cross-platform players; ALAC is required for native playback on Apple devices, iTunes, and Logic Pro. The conversion runs entirely in your browser via WebAssembly.
The practical reason for this conversion is Apple ecosystem compatibility. AirPlay devices, HomePod, Apple TV, and the Music app on Mac and iPhone natively play ALAC files in Apple formats. FLAC support in Apple software is limited and has historically been absent or unreliable. If you manage a lossless music library and want it to play on Apple hardware without any re-encoding, converting from FLAC to ALAC is the right path.
Upload your FLAC file
Drop one or more .flac files onto the converter. Batch conversion processes multiple files sequentially.
Confirm the conversion
No settings to adjust: FLAC to ALAC is a purely lossless repackaging. The audio data and metadata (tags) are preserved.
Convert in-browser
The WebAssembly audio engine decodes FLAC and re-encodes as ALAC locally. No upload happens at any point.
Download the ALAC file
The output is saved as a .m4a file with the ALAC codec inside, ready to add to your Apple Music or iTunes library.
Frequently asked questions
Does converting FLAC to ALAC cause any quality loss?
No. Both are lossless formats. The decoded audio data is identical; you are only changing the compression container and codec, not the audio content.
What file extension does ALAC use?
.m4a, the same container as AAC. The difference is inside: an ALAC file contains lossless data while an AAC file contains lossy-compressed data.
Why does Apple Music not support FLAC natively on older devices?
Apple added FLAC support to iOS 11 and macOS High Sierra, but earlier devices and some Apple hardware (older Apple TV models, HomePod) still do not support it. ALAC is universally supported across all Apple products.
Does metadata (artist, album, track number) transfer correctly?
Yes. Tags from the FLAC file (Vorbis comments) are mapped to equivalent ID3 or iTunes atoms in the ALAC container.
Is ALAC open source like FLAC?
Yes. Apple open-sourced ALAC in 2011. It is implemented in ffmpeg and many open-source players, though FLAC remains the more widely adopted lossless format outside the Apple ecosystem.
