Instagram is a photo and video sharing social networking service owned by Meta Platforms. It allows users to upload media that can be edited with filters, be organized by hashtags, and be associated with a location via geographical tagging. Posts can be shared publicly or with preapproved followers. Users can browse other users' content by tags and locations, view trending content, like photos, and follow other users to add their content to a personal feed.

A Meta-operated image-centric social media platform, it is available on iOS, Android, Windows 10, and the web. Users can take photos and edit them using built-in filters and other tools, then share them on other social media platforms like Facebook. It supports 32 languages including English, Hindi, Spanish, French, Korean, and Japanese.

Users can upload photographs and short videos, follow other users' feeds, and geotag images with the name of a location. Users can set their account as "private", thereby requiring that they approve any new follower requests. Users can connect their Instagram account to other social networking sites, enabling them to share uploaded photos to those sites. In September 2011, a new version of the app included new and live filters, instant tilt–shift, high-resolution photographs, optional borders, one-click rotation, and an updated icon. Photos were initially restricted to a square, 1:1 aspect ratio; since August 2015, the app supports portrait and widescreen aspect ratios as well. Users could formerly view a map of a user's geotagged photos. The feature was removed in September 2016, citing low usage.
