The most universally compatible and standard favicon size for desktop web browsers is 32x32 pixels. For maximum compatibility with older browsers, a 16x16 icon is occasionally used, while modern high-resolution screens and desktop shortcuts prefer 64x64 or higher.

Using an ICO guarantees your website's icon will display correctly across all browsers, including legacy versions of Internet Explorer and edge cases.

Absolutely. Your privacy is fully protected. Our converter uses modern HTML5 technology to process your images completely within your own web browser. Your PNG files are never uploaded to any external servers.
