Frequently asked questions

How do I convert WMV to M4A?

Click “Choose Files” and select your WMV file (or drag it onto the page). M4A is already selected as the output, so just click Convert and download your M4A file when it’s ready.

Will the audio quality change?

The audio is saved at high quality (192 kbps by default). If the video’s soundtrack is already in a compatible format, it is copied without any quality loss.

Is it safe to convert WMV files here?

Your files stay on your device. Conversion runs inside your own web browser, so your files are never uploaded to our servers or anyone else’s. Nobody can see them, and nothing is stored after you close the tab.

Is the WMV to M4A converter free?

Yes, it’s completely free. There’s no sign-up, no watermark and no limit on how many files you convert. Each file can be up to 1 GB.

Can I convert several WMV files at once?

Yes. Add as many WMV files as you like and convert them in one go, then download them one by one or together as a ZIP file.
