IconWorkshop

IconWorkshop is the name used by several icon editing applications designed to create and modify icon images for software and operating systems. The most common use is editing and exporting icon resources in Windows ICO format and macOS ICNS format, as well as producing bitmap exports for applications. IconWorkshop provides drawing and editing tools, support for multiple layers, alpha transparency, and a range of color palettes, and can generate icons at multiple required sizes from a single source image.

Typical workflows include importing vector or raster artwork, refining shapes, applying effects, and exporting to ICO, ICNS, PNG, BMP, or JPEG suitable for application bundles or installers. Some versions offer batch processing, project files, and command-line options to integrate into build pipelines. The software is generally marketed as a specialized tool for icon designers and developers, rather than as a general image editor.

IconWorkshop has existed in various forms since the early days of icon editing software and has been produced by different developers. Availability has included Windows platforms, with some variants also supporting macOS, reflecting cross-platform needs of software teams.
