Expert Tips

What the pros know

Pro Tip

If you have a large collection of MMF ringtones from an old phone backup, convert them to WMA for easy browsing in Windows Media Player. Create a playlist to preview your entire collection quickly.

Common Mistake

Converting to WMA for use on Apple devices or smartphones. WMA has poor mobile support. Use MP3 instead if you need cross-platform compatibility.

Best For

Windows users who want to play old mobile ringtones directly in Windows Media Player without installing additional codecs or software.

Not Recommended

Don't use WMA if you plan to share files with Mac users, use them on smartphones, or need universal compatibility. MP3 is better for those scenarios.

No such device? MMF to MP3 plays on everything, Windows included, and is the better default.
