Frequently asked questions
What image should I use for an ICO favicon?
Start with a square PNG, ideally 512 x 512 or larger. The tool creates multiple favicon sizes inside one ICO file for browser compatibility.
Which ICO sizes are included?
By default this converter includes 16, 32, 48, 64, 128, and 256 pixel PNG frames inside the ICO container. These sizes cover common desktop and browser favicon usage.
Can I use the ICO in WordPress?
Modern WordPress prefers a site icon uploaded in the Customizer, but an ICO file is still useful for older themes, manual favicon setup, or compatibility with legacy browsers.
