What it does

Icon Forge helps developers turn regular images into app-ready .ico files without manually resizing, cropping, exporting, and stitching icon assets together. Start with an image, choose the icon sizes, preview the result, then export files that are ready for Windows desktop apps.

Why developers use it

It is useful for PyInstaller builds, Tkinter and CustomTkinter apps, desktop app icons, favicon-style project assets, and fast software branding when you need a clean Windows icon without opening a heavy design tool.
