The Evolution of PuTTY's Icons: From Hand-Drawn to SVG

This article chronicles the evolution of PuTTY's icons from hand-drawn images in the 1990s to today's scalable SVG vectors. The author initially created 32x32 pixel icons using the MSVC icon editor, constrained by the 16-color palette and display technology of the time. Over time, to accommodate higher resolutions and the needs of various tools, the author refined the process, eventually developing a script that auto-generates icons in multiple sizes and formats. This culminated in SVG versions, achieving true scalability. The design philosophy remains simple and clear, reflecting PuTTY's 'reassuringly old-fashioned' style, and continues to be used to this day.
