Our initial result was good. We recommend Google's "Rabbi" Swiffy if you want to convert from Flash SWF to HTML5. It worked for us on a fairly complicated Flash animated graphic.
Note, this free converter works in beta mode for small Flash files, a typical Google limitation. If you try a larger one you get told, “Sorry, Swiffy currently does not convert SWF files larger than 1024 KB.”
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 can't yet convert DoubleClick Studio creatives.
...Swiffy 5.0 introduces experimental support for ActionScript 3.0.
Swiffy can be used in two ways:
- With the Swiffy Extension, you can directly publish to HTML5 from Adobe Flash Professional.
- On the Swiffy homepage, you can upload your SWF file to convert it to HTML5.
