Swiffy from Google

Google unveils Swiffy, taking your SWF files and turning them into HTML5  that will run in most modern browsers (Safari and Chrome for example) this also allows you to reuse Flash content on devices without a Flash player like the iPhone or iPad.

The converted file is pretty close in size to the original; however, the company warns that the project is fresh out of the oven, so it won’t convert your entire Flash library just yet.
