Swiffy is available at Google Labs, where the search giant's engineers create experimental applications that may not be ready for primetime or intended for the masses. Using the Swiffy website, anyone can upload an SWF file and convert it to HTML5.
Swiffy supports most of the Flash 5 ActionScript specification. The output file works in all browsers based on Apple's open-source Webkit engine, which powers the Mobile Safari browser found on the iPhone, iPad and iPod touch.
Also available on the site are a gallery of videos and games that have been converted to HTML5 from Flash, as well as a list of frequently asked questions. Among those questions is a query about what Adobe, the creator of Flash, thinks of Swiffy.
"Adobe is pleased to see the Flash platform extended to devices which don't support the Flash player," the site reads. "The result is that anyone creating rich or interactive ads can continue to get all the authoring benefits of Flash Pro and have the flexibility to run the ad in the Flash Player or HTML depending on what's available on the system. Google and Adobe look forward to close collaboration around efforts like these."
Google has made moves to support HTML5 in the past, including conversion of videos on the popular Web video destination YouTube. But Google also still includes Adobe Flash Player embedded in its Google Chrome browser.
The company is also pushing its own video playback format dubbed WebM over the Apple-backed H.264 format. The search company believes that its own WebM format will "enable open innovation."
