How to Convert WMA to M4A

Upload a WMA file
Step 1

Add your WMA audio

Upload an unprotected WMA file to the online converter for a quick browser task, or add your files to UniConverter Desktop for a repeated or multi-file job. Check whether your specific WMA variant is supported before starting.

Choose M4A as the output format
Step 2

Choose M4A as the output

Select M4A in the online converter. In UniConverter Desktop, choose M4A and review the available output settings if you need more control; check the selected profile or finished file to identify its audio codec.

Download the converted M4A file
Step 3

Convert and check the result

Start the online conversion and download the M4A file, or run the conversion in UniConverter Desktop and save the results locally. Play a finished file in your intended app before moving the rest of a library.

Choose the Right WMA to M4A Workflow

Free Online Conversion

Use this free WMA to M4A converter online with no signup or login when you need a convenient one-off result without setting up a larger desktop workflow.

A Clear Library-Migration Direction

Keep WMA as the input and M4A as the output when preparing older, unprotected audio for an M4A-based library. Test the result in your intended listening app.

A Check for WMA Variants

Confirm support for your particular WMA 8/9 file before converting. Treat WMA Lossless as a separate case rather than assuming every .wma file works the same way.

Local Desktop Workflow

Use UniConverter Desktop for larger files or repeated conversions when you prefer to manage the workflow on your computer.

Batch Jobs and Output Control

UniConverter Desktop supports batch conversion for multiple files and offers stronger output control than the simplified online workflow.

Support Beyond This Format Pair

UniConverter supports 1000+ video, audio, and image formats across the broader product, not necessarily in the online converter alone.

FAQs About WMA to M4A Conversion

Do not assume either type is supported. Check whether the file is protected and verify support for its specific WMA variant; WMA Lossless should be checked separately from WMA 8/9.
The codec cannot be determined from the .m4a extension alone. Check UniConverter’s current format specifications, the selected Desktop output profile, or the finished file’s properties rather than assuming a codec.
No, conversion cannot restore audio detail already lost from a lossy WMA source. The audible result depends on the source and output settings, so listen to the finished file before migrating a library.
Yes, the browser-based entry point is free and requires no signup or login. Check its current file and free-use limits before uploading; use Desktop if you need a larger or repeated workflow.
Yes, UniConverter Desktop supports batch conversion for multiple files. Use the online converter for a quick, usually one-off conversion rather than a batch job.
