- description
- Generate web UI/UX icon assets (favicon.ico, apple-touch-icon, PWA icons incl. maskable) and optionally Unreal Engine packaging icons (Windows .ico, macOS .iconset/.icns, Linux .png) from a single source SVG/PNG; use when you need correct multi-size icon files, safe-area guidance, manifests/head tags, or automation.
Icon Generator
You generate icon asset bundles for web UI/UX first (favicons + PWA icons), and you can also generate Unreal Engine packaging icon assets when needed.
Fast workflow
- Pick target(s): Web UI/UX (favicon + PWA icons) and/or Unreal Engine packaging (optional).
- Pick the source icon: prefer a 1024x1024 PNG (square) or a clean SVG. If it's not square, choose whether to crop or pad (default: pad).
- Generate the assets using
scripts/generate_icons.py.
Web/PWA sizes and safe-area rules: references/web-ui-ux.md
Unreal Engine formats and expectations: references/unreal-engine.md
Full size tables: references/icon-sizes.md
- Verify output quality: ensure the
.icocontains multiple sizes, and the 16/24/32 px variants are crisp.
Quality rules (what "good" looks like)
- Design for small sizes: avoid thin strokes, tiny text, and busy details.
- Prefer transparent backgrounds for desktop icons unless you intentionally "plate" the icon.
- Preview at 16px and 24px. If it becomes muddy, create a simpler variant.
Automation (recommended)
Run and customize the script:
- Script:
scripts/generate_icons.py - It supports:
- Web/PWA set: favicon.ico, apple-touch-icon.png, icon-192.png, icon-512.png, icon-maskable-512.png - UE sets (optional): Windows .ico, macOS .iconset, Linux .png
If you need HTML <head> snippets, manifest.webmanifest examples, and maskable safe-area guidance, read:
Notes
- If your input is SVG and Python SVG rasterization is unavailable on your machine, export a 1024x1024 PNG first (e.g., Inkscape), then rerun the script using the PNG.
- Keep this SKILL.md lean; detailed size tables live in the reference files.
