An SWF file is an animation that may contain text, vector and raster graphics, and interactive content written in ActionScript. It is saved in the Adobe Flash format, which was discontinued by Adobe on December 31, SWF pronounced "Swiff" files were commonly used to bring animated graphics, video, and sound to the web in the s and s. They were also a popular means of delivering browser-based games.

The byte codes support the language of ActionScript, whose model is provided by flash player at runtime for collaboration with servers and drawing primitives. Another characteristic of this format is its portability, it can be transported over a network having a low and unpredictable bandwidth.
In a low bandwidth environment, incremental rendering through streaming and file compression techniques are used to get the maximum benefits. The SWF file format is a binary format that keeps the file size small while bit-packing and structures are the commonly used techniques.
The format keep simple to facilitate Flash Player which can be easily ported. Files themselves are self-sufficient in a way, there is no need of any external resource such as fonts. With limited resources hardware the files work well and can take advantage of better resources when resources improve. This capability is vital because monitors have diverse resolutions and bit depths. This format was originally designed by FutureWave Software, to display animations with intention to run on a player software on any system with slower network connections, while keeping the file size small.
They tried to capitalize Macromedia Shockwave on the already established brand. In , Macromedia was acquired by Adobe, who announced the SWF as a part of its open source project in Remember, different programs may use SWF files for different purposes, so you may need to try out a few of them to be able to open your specific file.
