What is an SWF file?
SWF (Small Web Format, originally Shockwave Flash) is a binary file format for multimedia, vector graphics, and ActionScript execution, originally developed by FutureWave Software and later acquired by Adobe Systems. It serves as the compiled delivery format for Adobe Animate (formerly Flash) and relies on the SWF file structure specification to define tags for display lists and control bytes. Adobe officially ended support (End of Life) for the Flash Player runtime on December 31, 2020, rendering SWF files obsolete for web use due to security vulnerabilities and the shift to HTML5 standards.
How to open an SWF file
Modern web browsers (Chrome, Edge, Safari) strictly block SWF execution. To open legacy SWF files, users must rely on the standalone Adobe Flash Player Projector (content debugger) or open-source emulators like Ruffle, which runs Flash content via WebAssembly. For video-only SWF files not relying on complex ActionScript interactivity, VLC media player can often decode the embedded video streams.

What is a GIF file?
The Graphics Interchange Format (GIF) is a bitmap image format developed by CompuServe in 1987, distinguished by its use of the Lempel-Ziv-Welch (LZW) lossless data compression algorithm. It supports up to 8 bits per pixel, allowing a palette of 256 distinct colors selected from the 24-bit RGB color space. The GIF89a specification, introduced in 1989, added support for transparent backgrounds, animation delays, and application extensions, establishing it as a standard for simple web animations and low-color graphics.
How to open a GIF file
GIF files possess near-universal compatibility and can be opened natively by all modern web browsers (Chrome, Firefox, Safari, Edge) and default operating system viewers like Microsoft Photos and Apple Preview. No third-party software is typically required for viewing. For editing frame-by-frame animations or modifying color palettes, raster graphics editors such as GIMP, Adobe Photoshop, or online tools like Ezgif are required.
