Limits to know before using it

ICO exports are raster images. Tiny dimensions lose fine detail; the converter does not add favicon tags to your website.

Data handling and cost

Frequently Asked Questions

You can choose any combination of 16, 32, 48, 64, 128, and 256 px. All selected sizes are embedded in a single .ico file. Browsers pick the most appropriate size automatically.

For a standard favicon, 16 and 32 px cover most browsers. Adding 48 and 64 px improves display on high-DPI screens and in Windows taskbars. 128 and 256 px are useful for desktop shortcuts.

ICO Converter produces a single .ico file from your image. Icon Generator produces a full icon bundle (multiple PNG sizes + ICO + HTML snippet) intended for complete site icon setup.
