SWF files to HTML5

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.

Goahead and convert it here

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. It has  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.

Swiffy is a great example of how far the web platform has come. Swiffy animations benefit from the recent advancements in JavaScript execution speed and hardware accelerated 2D graphics in the browser. Viva la Web!
