ASF vs SWF:
| Name | ASF | SWF |
| Full name | Advanced Systems Format | Small Web Format |
| File extension | .asf | .swf |
| MIME | video/x-ms-asf, application/vnd.ms-asf | application/vnd.adobe.flash-movie |
| Developed by | Microsoft | Adobe Systems |
| Type of format | Digital container format | Vector graphic animation |
| Introduction | Advanced Systems Format (formerly Advanced Streaming Format, Active Streaming Format) is Microsoft's proprietary digital audio/digital video container format, especially meant for streaming media. ASF is part of the Media Foundation framework. | SWF is an Adobe Flash file format used for multimedia, vector graphics and ActionScript. Originating with FutureWave Software, then transferred to Macromedia, and then coming under the control of Adobe, SWF files can contain animations or applets of varying degrees of interactivity and function. They may also occur in programs, commonly browser games, using ActionScript. |
| Technical details | The format does not specify how the video or audio should be encoded; it just specifies the structure of the video/audio stream. This is similar to the function performed by the QuickTime, AVI, or Ogg container formats. One of the objectives of ASF was to support playback from digital media servers, HTTP servers, and local storage devices such as hard disk drives. | Programmers can generate SWF files from within several Adobe products, including Flash, Flash Builder (an IDE), Adobe Animate (the replacement for Adobe Flash as of Feb. 2016), and After Effects, as well as through MXMLC, a command-line application compiler which forms part of the freely-available Flex SDK. |
