Many folks include GIFs in their posts. GIFs could get your posts more attention, but they could also slow down your pages. By replacing your GIFs with a preview image, you can speed up your pages and allow your visitors to view your GIFs when they want. GIF Animation Preview happens to be a simple plugin that helps you add GIF previews to your site.
GIF Animation Preview is a simple plugin that replaces all your GIFs, whether embedded from other sites or from your library with a preview image. It grabs the first animation of the image and saves it to your media library directory. You can use the plugin to always preview or lazy load on single post pages. You can also enable the preview feature on mobile devices.
GIF Animation Preview does the heavy lifting for you and makes your GIF-heavy site more responsive. This is a free plugin.
