If you’re worried about iOS visitors on your flash based website, stop that today. Google has cooked Swiffy in their labs that converts your SWF animations into HTML5 preserving the animation and the file size. We couldn’t test our own flash banners as Google has put a limit of 512KB on input flash animation. Moreover not all flash elements may convert successfully but we have high hopes from swiffy once it gets seasoned.
In sample gallery Google has shown two flash based game examples which works fine in HTML5. This shows not only animations, but other elements like controls and responses to those controls also gets converted to html5. To convert your SWF files to HTML visit this link: Google Swiffy
