What GIF service does Instagram use?
Instagram's built-in GIF search uses the GIPHY library for features such as GIF comments and Story stickers. Meta's GIF-comment instructions direct users to tap the GIF icon to search GIPHY. Availability can differ by surface and account, and uploading your own GIF file as a feed post normally requires converting it to video first. See the Instagram GIF guide for comments, DMs, Stories, and posts.
