3GP.FM - Free Cell Phone Ringtone Maker Service

3GP.FM is an online service that allows users to freely generate mobile phone ringtones. However, since it originates from Japan, where the application of QR Codes for mobile phones is widely used, it is still unclear whether this service will suit domestic users in other countries. This introduction purely focuses on the service itself. It allows users to upload music files less than 15MB (in mp3 or m4a format). After uploading, the system automatically generates a QR Code image, which can be converted by a mobile phone to obtain the following URL:

After that, you can download the ringtone directly to your phone.
