Google has recently launch converting SWF files to HTML5 with Google Swiffy which is a free to use web application tool.
It supports many common SWF features such as vector graphics, embedded fonts, images, timeline animation and basic ActionScript 2.0.
The output works only in WebKit browsers as it includes some SVG features that are not supported by other browsers.
The usage is very simple: just upload the SWF file and Swiffy will display the HTML5 result where you can “save as” the page and insert into any website with an <iframe> tag.
P.S. The code generated by Swiffy is pretty complex and hard to edit. You’ll still need the .FLA file for editing the source.
