How do I convert an MP4 file to WMA audio?

Upload your MP4 file using the form on this page, select 'WMA' as the output format, and click Convert. The tool will extract the audio track and encode it as a WMA file. After the conversion finishes, download the WMA file to your device. You can also batch-convert multiple MP4 files simultaneously—just upload all of them and start the batch process.

Why should I convert MP4 to WMA instead of keeping the MP4 file?

MP4 is a video container; its audio is usually compressed as AAC or MP3. WMA is a dedicated audio codec designed by Microsoft, offering better compatibility with older Windows Media Player, portable media players, and car stereos that lack MP4 support. Converting to WMA also removes the video track, slashing file size by up to 90% if you only need the audio—perfect for music collections and podcasts.

How does MP4 to WMA conversion affect audio quality?

The conversion decodes the MP4's audio stream and re-encodes it using the WMA codec. The WMA encoder applies lossy compression, so some high-frequency information may be lost, especially at lower bitrates. You can select a constant bitrate from 64 to 320 kbps to balance quality and file size. The tool preserves the original sample rate and channel count (e.g., stereo stays stereo), but surround sound tracks are automatically downmixed to stereo unless you enable multichannel encoding in advanced settings. Metadata like title, artist, and album is copied but can be edited after conversion.
