Questions

How do I convert AIFF to M4A?

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

Is my AIFF 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.

Will I lose quality?

M4A is a compressed format, and Anyfile saves at high quality, so the difference is very hard to notice. For no loss at all, keep the AIFF.

Can I convert several AIFF files at once?

Yes. Drop them together and you get one ZIP with every M4A inside.
