Google Swiffy

Google Swiffy is a software tool released by Google Labs in June 2011. Swiffy is used to convert an Adobe Flash/Flex project into HTML5.

Google Swiffy allows a developer to convert a Flash animation into a browser viewable format, eliminating the need for a Flash player plug-in.

Google Swiffy takes a compiled Flash/Flex file (known as a SWF file because of its .swf file extension) as input. Swiffy converts the SWF file into an HTML5 file, Cascading Style Sheet 3 (CSS3) file, JavaScript (JS) and Scalable Vector Graphics (SVG).

There are two phases to the Swiffy conversion process, as follows:

• The Swiffy compiler reads the input SWF file and generates a JavaScript Object Notation (JSON) file.
• The JS client runtime uses the JSON file to generate HTML5, CSS3 and SVG files.

The HTML5 output file may then be embedded in a website.

Issues with the original Swiffy release included:

• Swiffy output only ran on browsers that supported SVG.
• Swiffy output was not easily editable by developers.
• Swiffy only supported ActionScript 2.0 conversion, although ActionScript 3.0 was available.
