Tags and cover artTitle, artist, album and cover carried over where AIFF holds them; lyrics and some rarer tags aren’t yet

Questions

How do I convert M4A to AIFF?

Drop your M4A file on this page, or choose it. Anyfile converts it on your device in a moment and the AIFF downloads straight away. To change it first, open it in the audio editor.

Is my M4A file uploaded anywhere?

No. The file is read and converted by your own browser, and nothing is sent to a server. You can check: open your browser’s developer tools, go to Network, and convert a file. No upload appears.

Can I convert several M4A files at once?

Yes. Drop them together and you get one ZIP with every AIFF inside.
