What is an SWF file?

SWF (pronounced “swiff”) stands for Shockwave Flash. It’s a format for audio, video, and interactive content developed by Macromedia and later Adobe. Loosely speaking, Flash brought the movement to the screen. 10 to 20 years ago, even entire websites were built with Flash – you may remember those days.

But later, Flash proved to be highly problematic. Adobe Flash Player, the browser plug-in for Flash files, had numerous security vulnerabilities. Flash content was too bulky for mobile devices and consumed too many resources. So Flash was gradually displaced by GIF animations and HTML5.

By 2021, Adobe Flash Player will no longer be available. But what can you do if you still want to open an SWF file?

Open an SWF file without Adobe Flash Player.

Because of serious security vulnerabilities, experts advise against installing Flash Player in your browser. However, there is a separate player for SWF files that you can download here – at least until the end of 2020 (currently [May 21], the debugger is still available there). The program is called Flash Player Projector Content Debugger, and there are versions for Windows, Mac and Linux.

Download Flash Player Content Debugger

The Windows version of the debugger is an executable EXE file that is about 16 MB in size. No installation is required.

Start the debugger. An empty white window will open. Click on File > Open.

Click on File then Open

Click Browse… to open a locally saved SWF file.

Navigate to the SWF file you want to play, and then click OK.

Click Browse then OK

Let’s go! Flash Player Projector Content Debugger plays your file without any problems. To pause or resume playback, open the Control menu. You can also use the keyboard shortcuts displayed in the menu.

So, SWF files are a relic of times gone by. As of 2021, the format is officially no longer supported. But as long as you still have Flash Player Projector Content Debugger on your computer, you can still open SWF files.
