How to convert PNG to ICO for a website favicon

2 Select the favicon sizes you need. The most common are 16×16 and 32×32, which are required by most browsers.
3 Optionally include larger sizes (48×48, 64×64, 128×128, 256×256) for high-DPI displays and bookmark icons.

A favicon is the small icon displayed in browser tabs, bookmarks, and address bars. The ICO format is the traditional favicon format supported by all browsers. While modern browsers also support PNG and SVG favicons, ICO remains the most universally compatible format and is especially important for older browsers and applications that display bookmark icons.

Multi-size ICO files contain several versions of your icon at different resolutions. The browser automatically selects the best size for the context — 16×16 for tabs, 32×32 for taskbar shortcuts, and larger sizes for bookmarks and high-DPI displays. Including at least 16×16 and 32×32 ensures your favicon looks sharp everywhere.

For the best results, start with a square PNG image that has clear, simple graphics. Favicons are displayed very small, so complex logos or text may not be legible at 16×16 pixels. Consider creating a simplified version of your logo specifically for favicon use. The converter uses high-quality downscaling to produce the sharpest possible result at each size.
