Convert Flash SWF files to HTML5 Online with Swiffy from Google
Google Labs launched an experimental tool called Swiffy.
Swiffy converts Flash SWF files to HTML5, allowing you to reuse Flash content on devices without a Flash player (such as iPhones and iPads).
Swiffy currently supports a subset of SWF 8 and ActionScript 2.0, and the output works in all Webkit browsers such as Chrome and Mobile Safari. If possible, exporting your Flash animation as a SWF 5 file might give better results.
