What is Bobcorn?

Bobcorn is a free, open-source desktop application for icon management and icon font generation. It helps designers and front-end developers organize large SVG icon libraries and generate production-ready icon fonts in every major format.

Who uses it: Individual designers, front-end developers, and enterprise teams (including ZTE and Shopee) who need to build and maintain custom icon font systems.

How it compares: Unlike browser-based tools like IcoMoon, Bobcorn is a native desktop app that handles large libraries (3,000+ icons) with fast local processing. Unlike macOS-only tools like IconJar, Bobcorn runs on Windows and macOS, and generates icon fonts — not just icon organization.
