Like it or not, GIFs have pretty much become the de facto language of the Internet, and few services are as good of a place to find and share them as Tumblr. With that in mind, it’s only natural that the service have its own built-in GIF maker, which was just added to Tumblr’s mobile apps earlier today. All users need to do is select a video or set of photos and convert them. After that, you can edit them however you want or just post them as is.
