Part 2: Why Convert SWF to MP4?

MP4 or MPEG-4 video file format is a widely used multimedia' container format' typically used to store videos, audio, and other data files in a smaller file size. The format works with a wide range of devices and is used to share, download and stream video content.

SWF or Small Web Format is a Shockwave Flash Movie file created by Adobe with a file extension as .SWF. This Adobe Flash file format is used for multimedia, vector graphics, and ActionScript. They are generally used for online games as animation files that usually hold interactive texts and graphics. These Shockwave formats are generally used when users share online tutorials requiring audience interaction.

SWF format is suitable for interaction; you cannot upload them on social media or YouTube. Though it is excellent for encoding browser-based games and animations, the format is incompatible with famous media players. And sadly, SWF files can be opened on Adobe Flash Player only.

On the contrary, MP4 is a highly compatible video file format that runs on all social media platforms like YouTube, Twitter, TikTok, Facebook, etc. Moreover, these files can easily be played with almost all media players like VLC, Windows Media Player, QuickTime, and more. And as Adobe now no longer supports the SWF file format owing to its security issues, users are compelled to uninstall or convert SWF to MP4 files.
