Icon Maker

A small Rust desktop app for converting SVG files into icon assets.

Outputs

• Win64 application icon: creates a multi-resolution .ico file with 16, 24, 32, 48, 64, 128, and 256 px entries.
• UI raster icon set: creates transparent PNG icons at common UI sizes, defaulting to 16, 20, 24, and 32 px.

In-app icons

The application UI itself follows the egui-phosphor format: Phosphor icons are loaded as an egui fallback font and referenced by Rust constants such as egui_phosphor::regular::FILE_SVG.

That is different from exporting arbitrary SVGs. A Phosphor-style egui icon library is a font plus Rust glyph constants; a normal SVG can be rasterized into PNGs or ICOs, but it is not automatically a font-backed egui icon without a separate font-generation step.

Stack

The app uses off-the-shelf crates for the hard parts:

• eframe / egui for the desktop UI
• egui-phosphor for in-application UI icons
• rfd for native file/folder pickers
• usvg / resvg / tiny-skia for SVG parsing and rasterization
• ico for Windows .ico writing
• image for PNG output
