Facebook announced support for the animated GIF files format. However, there are few restrictions.
She further added that GIF links from Tumblr were not displaying properly in display mode, but worked fine after posting.
It was also noted by her that the Facebook support for the GIFs was extended to its flagship mobile applications, but not to the pages. Warren finally suggested that Facebook users who are looking to share GIFs from services such as Giphy, Imgur and GFYcat should use the full URLs for the GIFs in their posts on the social network, as there were coding issues when using the Flash or HTML versions of the images that are created by the services.
In a statement to TechCrunch, Facebook confirmed its support to GIFs, “We’re rolling out support for animated GIFs in News Feed. This is so you can share more fun, expressive things with your friends on Facebook.”Limited Support For Animated GIF File Now Available On Facebook!,
