About PNG to ICO
ICO is the classic Windows icon and favicon format, and one .ico file can hold several sizes. This tool renders your image at 16x16, 32x32 and 48x48 pixels and packs all three, PNG-encoded with transparency, into a single favicon.ico that browsers and Windows can pick from.
When it helps
- Creating the favicon.ico that browsers request from the root of your website.
- Making a desktop shortcut or application icon for Windows.
- Converting an existing JPG, WebP or BMP logo into an icon file.
Tips
- Start from a square image. A non-square image is stretched to fit the square icon sizes.
- Simplify the design for tiny sizes: at 16x16 pixels, thin lines and small text disappear. A bold mark or single letter reads best.
- If you need Apple touch icons, Android icons and a web manifest as well, the Favicon Generator builds the whole pack.
