How it Works

Generates multi-resolution icon layers (16x16, 32x32, 48x48) from your square images and packs them into a single, standard .ico file client-side for tab indicators.

Best Practices

Use square PNG source files with transparent backgrounds for clean favicon look.
Check the preview icons list to ensure details are legible at 16x16 pixels.
Download the complete favicon pack to cover both legacy and modern device requirements.

Frequently Asked Questions (FAQ)

Q: What is an .ico file?

A: An ICO file is a specialized container that bundles multiple resolutions of an icon, allowing the browser to select the optimal resolution dynamically.

Q: What is the recommended size for a favicon?

A: A standard favicon should contain 16x16, 32x32, and 48x48 sizes inside the ICO file. Modern browsers also use 180x180 PNGs for mobile touch icons.

Q: Can I make a favicon from SVG?

A: Yes, our favicon tool renders the SVG source code directly into all required icon sizes.
