Desktop converters require downloads. Online converters upload your files to unknown servers. AudioUtils does neither. It runs WebAssembly in your browser tab.
The conversion is fast. A typical 5-minute audio file converts in under 3 seconds. No progress bars that stall at 99%.
M4A is lossy. Converting to FLAC won't restore lost data, but gives you an uncompressed container for editing workflows. Works on Chrome, Firefox, Safari, and Edge. Any device, any OS.
Frequently Asked Questions
Does converting M4A to FLAC improve audio quality?
No. M4A typically uses lossy AAC compression, and that lost data can't be recovered. FLAC stores the audio losslessly from this point forward, preventing further degradation.
Why convert to FLAC if it doesn't improve quality?
FLAC is open-source and supported by nearly every media player outside Apple. It also preserves the current quality exactly — no further loss from future format conversions.
Will FLAC files be larger than M4A?
Yes, typically 3-5x larger. FLAC is lossless, so it stores more data per second of audio than the compressed M4A source.
