Affinity Photo began as a raster graphics editor solely for macOS. It was Serif's second macOS app, and was built from the ground up to leverage core native technologies, including Grand Central Dispatch, Core Graphics, OpenGL and Metal 2hardware acceleration. Serif established an R&D team for Affinity Photo in 2009, headed by lead designer Andy Somerfield. A free beta test version of the Affinity Photo app was released to the public on 9 February 2015. The initial stable release of Affinity Photo, version 1.3.1, launched on the Mac App Store9 July 2015 for macOS 10.7 and later. At that time, Serif's raster graphics application for Windows was PhotoPlus; however, following the release of Affinity Photo for Windows, this product has now been discontinued. Version 1.3.5 of Affinity Photo, released in August, provided numerous bug fixes and improvements. Serif announced its first major update to Affinity Photo in December 2015.

Stability and bug fixes were released with Affinity Photo 1.4.1 and 1.4.2, in January and June 2016. Version 1.4.3 in September 2016 optimised Affinity Photo for macOS 10.12 Sierra. In December, 2016, Serif launched Affinity Photo for Windows, and released an update to the macOS version at the same time, Affinity Photo 1.5.1 added a 32-bit RGB editing mode with support for 32-bit file formats and more than 70 new camera RAW file formats, as well as the ability to develop RAW files directly into a 32-bit document. Version 1.5.1 also added support for the new MacBook Pro with Touchbar. Serif launched Affinity Photo for iPad during the keynote at Apple's WWDC in San Jose on 5 June 2017.
