What is a SWF File Type?
In the 2000s and 2010s, SWF files were commonly used to bring animated graphics, video and sound to the web. It was also a popular way to offer browser-based games. As web technologies improved, however, Flash became increasingly criticized for its flaws, which included performance and security issues. Adobe and many web browser developers announced that they were officially shutting down Flash support at the end of 2020.
SWF (sharp &" Swiff &") was originally an acronym for " Shockwave Flash &" since the SWF format was designed for Shockwave Player. As SWF files have become a standard medium for posting Flash content to the Web, however, the acronym has been changed to mean Small Web Format as well.
Because the SWF files contain compressed media and ActionScript compilations, they are not meant to be edited. To modify a Flash animation it is recommended to edit the original .FLA file instead.
Flash was developed by Macromedia, which was acquired by Adobe Systems in 2005.
