It seems like a long time coming, especially with the popularity of GIFs on the internet, but the wait is finally over. Instagram is rolling out to both Android and iOS users a new GIF button with the GIFs you can add provided by GIPHY. Just like how it’s done on other platforms, you can browse through trending GIF stickers or look for specific ones to add to your photo or video story.
Aside from that, Instagram users can expect in the near future the ability to upload photos and videos “of any size” into a story, similar to what you can do with Stories on Facebook. So instead of cutting off a part of an image or video, Stories will show the entire photo or clip in its original state. Any extra room will be filled by a color gradient to match the colors of the image or video.
