Explanation: SWF is a file extension for a Shockwave Flash file format created by Macromedia and now owned by Adobe. SWF stands for Small Web Format.

Flash has a better performance than HTML, as a comparison of Flash with HTML in 2010 listed Flash as being faster than the other technologies, when used for non-video animations, although they are catching up.

Flash files will have the “. swf” extension.

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.

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.
