Well, there are a couple of font converter softwares available over the Internet. However, please note that I have used none of them and as such would not be able to vouch for them.
Online Font Converter
This online tool claims to be capable of converting fonts of all types. You can reach it at https://onlinefontconverter.com/
This is again an online tool. It uses a simple interface wherein you can convert any of your font between different formats. It is also known to support some lesser known font formats. You can find it at http://www.freefontconverter.com/
Please note that I cannot assure of the authenticity of these tools.
