What is SWF?

SWF stands for Small Web Format, a file format used for multimedia, vector graphics and ActionScript code in Adobe Flash animations. SWF files are often used to create interactive multimedia content such as animations, games and advertisements that can be embedded in web pages. They can also be used for standalone applications or mobile apps. Besides, SWF files can contain various multimedia content, including vector graphics, images, audio, and video. Additionally, SWF files are platform-independent and can be played back on both Windows and Mac operating systems, as well as on mobile devices that support the Adobe Flash Player plugin. While SWF was once a popular format for creating interactive multimedia content, it has largely been replaced by newer technologies such as HTML5, CSS3, and JavaScript, which offer similar capabilities without the need for a plugin. However, some legacy content is still available in SWF format and some websites may still use the Flash Player plugin to play back SWF files.

What is FLV?

FLV, short for Flash Video, is a file format used to deliver video content over the internet. FLV files are typically small in size, making them ideal for streaming video content over the internet. They can be embedded in web pages and played back using the Flash Player plugin or other media players that support the FLV format. Besides, they can contain both video and audio data, and support a variety of codecs, including H.264, VP6, and MP3. Much as FLV files are replaced by newer video formats such as MP4 and WebM, some legacy video content may still be available in the FLV format and Flash Player plugin is still adopted by some websites to play back FLV files.
