Modernizr: the feature detection library for HTML5/CSS3. Swiffy. As part of our transition of display ads to HTML5. the Swiffy Flash conversion tool is no longer available. We will continue to serve the Swiffy runtimes, so any files you have already converted will continue to play. Today more consumers are using the web in HTML5 compatible environments than Flash-compatible environments. In order to reach as large an audience as possible, we encourage everyone to transition to HTML5 authoring. Developers who currently create Flash SWF files have several ways to switch to HTML5 including Adobe Animate and Google Web Designer. If you need to play an existing Flash SWF file in your browser alone, you might be able to use Mozilla’s Shumway.
