M4A (.m4a) · Max 20 MB
M4A already discarded some audio data during its initial compression. Converting to FLAC wraps the remaining audio in a lossless container. No additional quality is lost.
This is useful when your editing tools require FLAC input. You get compatibility without a second round of lossy compression.
For the best results, always start from the highest quality source you have. If you have the original uncompressed recording, convert that instead.
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.
