For those who are paranoid after hearing the news from Adobe about Flash on mobile, Google has something that you can use. Swiffy is an extension for your Adobe Flash Professional (CS4 or newer).
It helps to publish Flash into HTML5 format in a click.
With the Swiffy Extension, you can publish to HTML5 right from Adobe Flash Professional. This makes using Flash to develop HTML5 animations much easier. The extension accesses Google Swiffy as a web service, so you always use the most recent version of Swiffy.
Here is the link to Swiffy.
