How to Create a Favicon from a PNG (ICO Guide)
Turn a logo PNG into an ICO favicon that works in browser tabs. Includes size tips and a private converter workflow.
What a favicon needs
A favicon is the small icon in a browser tab. ICO remains a reliable package format, and many sites still ship an .ico even if they also serve PNG/SVG icons.
Start from a simple logo on a transparent or solid background. Busy photos rarely read well at 16×16.
Recommended workflow
Keep the process short:
- Design or export a square PNG (ideally 512×512 or 256×256)
- Use the PNG to ICO tool — large images are scaled for favicon use
- Upload the .ico to your site root or public folder and link it in your HTML head
Design tips that survive tiny sizes
Simplify. High-contrast shapes beat thin lines. Test the icon at 16px and 32px before you ship it.
