icon

PuTTY icons evolved from hand-drawn designs in the late 1990s to a scripted generation system by 2007, maintaining a consistent, recognizable style. Each tool, like PuTTY, PSCP, Pageant, and PuTTYgen, has its icon, primarily depicting computer-related themes. Initial icons faced limitations in color palettes and sizes, but later enhancements included varied versions for different dimensions and true color outputs. In 2021, SVG versions were created for scalability. Despite suggestions for redesigns, the original 1990s style remains integral to PuTTY’s identity.
