HTML, Accessibility, Performance
1-minute read

If you care about web performance, please stop using gifs for animations on your website. Heck, even Giphy, the largest gif library in the world, serves gifs as MP4 files. Actual GIF format is their last possible fallback.

MP4, WebM, and WebP will almost always be 1/5 to 1/2 the file size of GIF, so there's an immediate benefit of faster page loads and better performance. Not only that, but HTML video elements have the benefit of fallbacks using source . If you've not used them before, here's a quick example of how to make a video element behave like a gif.

<!-- The easy way -->
<video src="animation.mp4" autoplay muted loop playsinline></video>
<!-- The easy way, but with fallbacks -->
<video autoplay muted loop playsinline>
  <source src="animation.webm" type="video/webm">
  <source src="animation.mp4" type="video/mp4">
  Your browser doesn't support embedded videos.

Pretty easy right? One quick note: When possible, always use the muted and autoplay attributes together. The reason for this is that most mobile browsers will ignore autoplay if muted is not also present.

Already use gifs in production on your site? Use a service like to convert them to MP4 and optimize them for the smallest possible file size. You'll be amazed at the results.
