Instagram is a social media app which lets users share photos and videos from their smartphones, as well as like and comment on other users posts, send private messages, search for relevant content, and more. Users can view their feed from any web browser, but can only upload photos and videos through the native apps for iOS and Android. Instagram includes a range of filters and editing tools which users can apply to their photos and videos before posting. The exposure, brightness, contrast, saturation, warmth, fade, and other aspects of photos can be adjusted, and users can also add text and drawings on top of their photos and videos. Up to 10 photos and videos can be published in a single post, and filters can be applied in bulk across a whole post, or to individual images. Videos can be shared with or without audio, and users can control which frame of a video is presented as the cover image. Captions, hashtags, and locations can be added to posts, enabling users to search for relevant content.
