About this tool
Converting FLAC to M4A
FLAC compresses audio losslessly — typically half the WAV size with every sample bit-identical. It is the archival format of music collectors and audiophiles. M4A is the Apple-native container around AAC audio — the default format of iTunes, iPhones, and voice memos on Apple devices. AAC-in-M4A encoding serves Apple devices at mobile-friendly sizes from the lossless master.
What to check after converting
Listen to a section you know well — the beginning, the loudest part — and compare it against the original file. Lossy re-encoding always applies: keep the original FLAC file as the master if you may need a higher-quality conversion later. Your original file stays untouched on your device either way.
Frequently asked questions
Will converting FLAC to M4A reduce the quality?
Lossy re-encoding applies a small additional quality step. At standard bitrates the difference is rarely audible; keep the original as your master regardless.
Is my audio file uploaded anywhere?
Small files convert entirely in your browser; larger ones finish on our servers and auto-delete within an hour. Either way, nothing is kept, shared, or used for anything else.
Why would I pick M4A over FLAC?
AAC-in-M4A encoding serves Apple devices at mobile-friendly sizes from the lossless master.
