Today we’re making the first version of Swiffy available on Google Labs. You can upload a SWF file, and Swiffy will produce an HTML5 version which will run in modern browsers with a high level of SVG support such as Chrome and Safari. It’s still an early version, so it won’t convert all Flash content, but it already works well on ads and animations. We have some examples of converted SWF files if you want to see it in action.

Swiffy uses a compact JSON representation of the animation, which is rendered using SVG and a bit of HTML5 and CSS3. ActionScript 2.0 is also present in the JSON object, and is interpreted in JavaScript in the browser. This representation makes the Swiffy animations almost as compact as the original SWF files.
