Adobe today released a tool, codenamed Wallaby, that converts Flash to HTML5.
After the drama surrounding the company’s Flash to iPhone conversion tool, Adobe is taking another crack at keeping Flash relevant as native web technologies catch up to the format’s capabalities.
The tool is still in experimental development, but can be downloaded here. Once your project is converted, you can work with it as you would any HTML file.
At this stage, some Flash Professional features are unsupported.
