SWF (Small Web Format, or Shockwave Flash) is a multipurpose multimedia format widely used on the web. It is also known by many other names (often conflated with the names of SWF players), such as Flash, Adobe Flash, Macromedia Flash, Shockwave Flash, and FutureSplash.
Fundamentally it is an animated vector graphics format, but it has many other features, and can contain complete computer programs written in ActionScript. Among its common uses are advertisements, web site user interfaces, video games and other applets, and video playback. This format is famously not supported by Apple's iOS devices, leading Web developers to support alternative means of accomplishing such things as video playing, such as those provided in HTML 5.
SWF is not designed to be editable. Instead, SWF files are usually compiled from a source (project) format called FLA. The ActionScript programming language is also used.
