ICO is the standard format for website favicons — the tiny icon that appears in browser tabs, bookmarks, and search results. If you have a logo or icon in PNG format, converting it to ICO is straightforward. Here's how.
How to Convert PNG to ICO
- Start with a square PNG (your logo or icon, 256×256 or larger recommended)
- Open the Image Converter
- Upload your PNG
- Select ICO as the output format
- Download the .ico file
- Place it in your website's root directory as
favicon.ico
ICO vs PNG Favicons
- ICO — Most universally supported. Can contain multiple sizes in one file.
- PNG — Modern browsers support PNG favicons. Good for simple setups.
- SVG — Best for modern browsers. Supports dark mode.
For maximum compatibility, provide both: an ICO for older browsers and a PNG or SVG for modern ones.
