SWF, short for Small Web Format, is a dated proprietary format from Adobe Flash that contains multimedia and animations. It requires Adobe Flash Player to play the file. However, with the discontinuation of Flash in 2021, the SWF format is effectively obsolete.

WebM is a modern, open source video format designed for web use. It’s based on Matroska (MKV) and stores VP8/VP9/AV1 video and Vorbis/Opus audio. Compared to SWF, WebM is more widely supported and future-proofing.

By converting SWF to WebM, you can benefit from several advantages, including

• Better compatibility: SWF is no longer supported due to the death of Adobe Flash in 2021, while WebM is still supported by major streaming platforms and browsers like YouTube, Twitter, Facebook, Chrome, Opera and Firefox.
• Royalty-free: WebM is open source and requires no license to use.
• Efficient file size: WebM can adopt more efficient compression technologies to produce high-quality video at smaller file sizes.
