Files with the extension SWF contain animations in Adobe Flash format. The abbreviation stands for Small Web Format.
Thanks to the cross-platform availability of the Flash Player as a browser plug-in, SWF files are very widespread on the Internet today.
SWF files can contain both vector and bitmap graphics as well as audio, videos, animations, text and links. A variety of interactive content, from presentations to the navigation of a website to games are also possible.
Flash has many advantages, including a fixed, cross-platform layout, independence from local resources such as fonts, interactive capabilities, and controllability. But has the disadvantage of not being an open standard.
Flash can also be streamed and protected by DRM (Digital Rights Management).
The contents of a SWF file can be extracted and modified with appropriate software.
However, many SWF converters only produce videos that lack the rest of Flash's ability. The production of fully functional SWF files requires authoring software.
