I like to develop a mobile website of my current desktop site.I saw there are couple of online tools to convert an existing website to mobile site.But i want to know is there anyway to develop a website by my own? **
I agree with LastMitch though, the only way I know you can convert your website to mobile is by a premium service or do it your self... but I am curious on what services that you (DeepAnalyzer) has found.
The link you provide is creating a Mobile website not converting an existing website into Mobile website. I think you misread it. Those platforms are intended to create a fresh Mobile website not converting an existing website into a Mobile website.
