About converting M4A to AAC
Audio formats differ in how they compress and in what will play them. Converting from a lossy format to a lossless one cannot restore what was discarded when the original was made — it only stops any further loss — so the honest reason to convert upward is compatibility, not quality.
How to convert M4A to AAC
Add your M4A file
Drag it onto the box above, click to browse, or paste it straight from your clipboard.
Check the settings
AAC is already selected. The defaults suit most files, and you can open Settings if you want to change the quality or size.
Download the AAC
Most files are ready in a second or two. Larger ones convert in the background while you watch the progress.
Quality
The file is re-encoded, so the AAC is visually equivalent rather than bit-for-bit identical. At the default settings the difference is not something you would notice.
