You can also download sonnerietelephone.com, which is a free ringtone maker. This application allows you to make ringtones from music files stored on your computer. It can load the file from a directory on your computer, but it only supports MP3 format. You will have an option to preview the ringtone before sending it to your recipient. You can also use a play button to listen to the ringtone before making the final selection.
The best way to download ringtones for free is to find the ones that suit your taste. You can even download a free music app, like Spotify, and listen to it before downloading. While you're at it, consider adding the ringtone to your social favorites so your friends can hear it too. You can also share the ringtone with others on the same network. Of course, the download option will not work with iPhone.
