Why Convert MP3 to M4A?
Need an M4A version of your favourite track? Our converter turns any MP3 into a crisp M4A file powered by the modern AAC codec. No software download, no waiting.

How to use the converter
Getting started is easy – drag the MP3 into the drop zone above or tap the upload button, then relax while we convert the file in the cloud. When it’s done, your download starts with a single click.

Always 100 % Free
The service is and will always be free. There are no usage limits, sign-ups or annoying pop-ups. We simply love smooth audio conversions.

Smaller Size, Better Sound
M4A usually delivers about 30 % smaller file sizes than MP3 while preserving better detail in the highs and lows. That means more songs on your device and clearer sound in your headphones.

Your Privacy Matters
Your audio belongs to you alone. Every file is encrypted during transfer and erased from our servers automatically within minutes after the conversion is finished.
