MP4 to M4A Converter

Add an MP4 file and this page rewrites it as M4A in your browser tab — nothing is uploaded to a server and nothing has to be installed. The soundtrack is lifted out of the clip intact, so check that the M4A result plays where the MP4 original would have needed its video track.

Frequently Asked Questions about MP4 Conversion

Do I need software to turn MP4 into M4A?

No. This page runs in the browser tab, so nothing has to be installed to produce the M4A result.

Can I convert more than one file at a time?

Add the files to the list, run the conversion once, and download the results together instead of repeating the upload per file.

Will my original file be changed?

The result is downloaded as a separate file. Keep your original until you have checked the M4A output.

What should I check before using the result?

Open the M4A output in the application that consumes it and spot-check the parts that matter to you; the original file stays untouched if you need to re-run with different options.

Why convert MP4 to M4A?

MP4 and M4A have different compatibility and editing characteristics. Convert when the next application or service requires M4A, then open the result and check the details that matter to your workflow.

Does MP4 to M4A reduce quality?

It can. The result may change compression, dimensions, color, metadata, layers, page layout, animation, or text structure. Use the available options and verify the output in the destination application.
