Affinity Photo Overview
Affinity Photo is a professional raster photo-editing application for Windows and macOS from Serif, positioned as a one-time-purchase alternative to subscription photo editors. It provides layers and masks, a non-destructive RAW develop workspace, advanced selection and retouching tools, focus stacking and HDR merge, panorama stitching, and a fast, GPU-accelerated engine that handles large images smoothly. It reads and writes many formats, including PSD, which eases moving files between tools. A key draw is its licensing: you buy it once rather than subscribing. It also includes a dedicated Liquify persona, advanced lens and perspective corrections, recordable macros for batch edits, and support for unlimited layers and adjustment layers within a single document. The official Affinity Photo download is linked on this page, straight from Serif.
