Frequently Asked Questions
What is an ICO file?
An ICO file is a binary image format used for icons in Windows applications and website favicons. It can contain multiple images at different resolutions, allowing browsers to display the appropriate size for different contexts.
What sizes should I include?
16x16 and 32x32 are the most common for browser favicons. Include 64x64 and 128x128 for Windows shortcuts and high-DPI displays. 48x48 is useful for legacy support. 256x256 is sometimes used for large icon representations.
How do I use the favicon on my website?
Place the favicon.ico file in your website's root directory, or reference it in your HTML with: <link rel="icon" href="/favicon.ico">. Most browsers will automatically find it in the root directory.
