While the GIF format is a little on the older side, it’s still a really handy format in 2025 for sharing short clips where an actual video file might have some compatibility issues.
For instance, I find when you just want a short little video on your website, a GIF is still so handy versus a video, where some browsers will refuse to autoplay them, or seem like they’ll autoplay them fine until Low Battery Mode is activated, etc. With GIFs it’s just… easy, and sometimes easy is nice. They’re super handy for showing a screen recording of a cool feature in your app, for instance.
There’s a 8 year old bug about missing Firefox Matroska support so it’s not as if there’s no video compatibility issues, especially if you also consider old and/or embedded versions.
