Should you convert FLAC to M4A?
Do this to make a lossless recording small enough to share or carry around. Keep the FLAC as the master copy.
FLAC is lossless and M4A is not
This is the conversion lossy formats were designed for: from 5 to 7 MB per minute to 1 to 1.9 MB. At 192 kbps or more almost nobody can hear the difference in music. Keep the FLAC as your master if you might need to convert again.
Where the M4A will play
M4A plays on Apple devices, Android, browsers and most modern players.

What usually goes wrong
About the FLAC. Converting an MP3 to FLAC produces a large file that sounds exactly like the MP3. Lossless compression preserves what it is given, including the damage.
About the M4A. M4A, M4B, M4R and AAC are largely the same thing with different extensions. Renaming usually works, though it is not something to rely on.
How to convert FLAC to M4A
- Add your FLAC file. It is read from your disk and stays there.
- Check the settings. The output format is already set to M4A.
- Press convert and the M4A file is saved back to your device.
Questions
How do I convert FLAC to M4A?
Open this page, add your FLAC file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this FLAC to M4A converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to M4A lose quality?
M4A is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
Can I convert several FLAC files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
