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 currently supports a subset of SWF 8 and ActionScript 2.0. Getting started with Swiffy.
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.
Both methods will always use the most recent version of Swiffy.
How Swiffy works
Supported features and browsers
Swiffy supports shapes, embedded fonts, timeline animation, (dynamic) text, movie clips, buttons and scripting using ActionScript 2.
Swiffy uses web standards such as SVG and EcmaScript 5, so over time more browsers will support Swiffy output.
Test the output in mobile browsers
Mobile devices are generally less powerful than the computer you are using to develop your animation, so it is essential to test the output on devices you are targeting. The Swiffy website makes this easy for you by giving you a QR code that you can scan to preview the output.
Take care when using filters
Swiffy supports filters, but animated SVG filters are computationally expensive and are not supported on all mobile browsers. When a filter effect is required, it might be better to convert the sprite including the filter to a bitmap.
Use the Swiffy extension to get feedback while developing
The Swiffy extension can be used to export to HTML5 directly from Flash Professional. If you regularly export your file, you will know immediately if Swiffy encounters a feature that is not supported.
