FLAC to M4A Converter
Runs in your browser — your files are never uploaded.
Convert FLAC to M4A so a lossless library will actually play on Apple hardware. Apple has never supported FLAC in iTunes, Apple Music or the iOS Files player, which leaves a collection ripped to FLAC unplayable on an iPhone. M4A with AAC is the format that ecosystem expects, and at a high bitrate the difference is inaudible to almost everyone.

Frequently asked questions
Am I losing quality?+
Yes — FLAC is lossless and AAC is not, so this is a one-way conversion. At 256 kbps the difference is inaudible to nearly everyone on nearly all material. Keep the FLAC files as your archive and treat the M4A as a playback copy.
Why does Apple not support FLAC?+
It has its own lossless codec, ALAC, which does the same job in an M4A container. ALAC was open-sourced in 2011, but FLAC support has still never appeared in iTunes or Apple Music.
Should I convert to ALAC instead to stay lossless?+
If space is not a concern, that would preserve the original quality exactly — but it produces files about the same size as the FLAC, which is usually the reason people are converting in the first place. AAC is the pragmatic choice for a phone.
Will my tags survive?+
Basic metadata carries over. Album art and less common tags may not, since the two formats store them differently — check one file before converting a whole library.
