Google Photos is an online, cloud-based photo storage system released by Google in 2015. It allows users to upload photos and videos that can be accessed and edited on multiple platforms using a Google account. These files, however, are reduced to 16 megapixels (1080p for video) to keep file size low. The service can be accessed for free on their website or using their mobile application for iOS and Android.
Google Photos also comes installed as the default photo storage application on the Google Pixel series of phones running stock Android. On this platform, the size of photos and video files are not reduced.
