Best Practices for PNG to ICO

📋 Before Converting
  • Prepare square PNGs (e.g., 16, 32, 48, 64, 128, 256px).
  • Use transparent backgrounds when needed.
  • Keep visuals simple at small sizes.
  • Export multiple resolutions for clarity.
  • Retain original PNGs for editing.
✅ After Converting
  • Verify favicon rendering on major browsers.
  • Test on Windows taskbar and Start Menu.
  • Check clarity at 16×16 and 32×32.
  • Serve favicon.ico at site root for legacy support.
  • Optionally add modern png icons in HTML.

Troubleshooting

Export exact pixel sizes (16, 32, 48, etc.) and simplify artwork.

Use anti-aliased edges and ensure a transparent background.

Bundle multiple sizes in the ICO; browsers pick the best fit.
