The first version of Swiffy, which can convert Flash SWF files to HTML5, is now available on Google Labs. You upload the SWF file and Swiffy does all of the work. All you have to do is take the resulting HTML code and include it on your website using an iframe tag. Swiffy works by converting the SWF file into a JSON file which your browser then loads with JavaScript and renders using HTML, SVG, and CSS.

Popular online video service Vimeo has converted their site to HTML5. What does that mean for you? Now you can watch all of their videos conveniently from any iDevice. Also, if you sign in to your Vimeo account, you can mark videos with the “Watch Later” feature. This lets you queue up a bunch of videos, perhaps for later in the day when you have more time to watch them.

It seems that this past Friday, rumors started to circulate that Apple will be launching Safari 5 as early as today’s WWDC keynote presentation. With it, Apple is believed to be taking aim at Google with features such as an option for Bing search engine integration (has Google really made bedfellows of Apple and Microsoft?) and at Adobe with increased HTML5 functionality.

In what is a classically underhanded-yet-still-crushingly-obvious Jobsian maneuver, Apple just gave Adobe a combined insult roughly equivalent to inviting the Queen of England over for tea and setting a box of Lipton tea bags in front of her. By launching a new site detailing iPad-ready websites, Apple has deftly altered the playing field in the HTML5 vs. Flash wars.

At MWC, Vic Gundotra, Google’s VP of engineering, demoed what many might think is heaven sent; offline Gmail (the web app) with, among other things, support for labels. Better yet, the technology doesn’t depend or even require you to jailbreak your iPhone. So, you won’t even have to get Apple’s panties all in a bundle to get it working.
