## How do I convert a file to M4A?

Open a supported conversion below, select the original file, review the available options and select Convert. Download the result before its temporary job expires. Re-encoding cannot recover sound already lost to compression. Use a destination format your player supports, then compare clarity, duration and file size. Video-to-audio conversion needs an existing audio track.
