Frequently Asked Questions
Should I use ICO or PNG for my favicon?
For maximum compatibility, use both: a favicon.ico (for legacy browsers and bookmarks) and PNG favicons for modern browsers. The ICO format is the only format guaranteed to work everywhere, including older IE versions.
What is a multi-size ICO file?
A single .ico file can contain multiple images at different sizes (e.g. 16×16, 32×32, 48×48). The operating system or browser automatically selects the best size. Our favicon-multi.ico contains 16, 32, and 48px variants.
What size should my favicon be?
16×16 for browser tabs, 32×32 for taskbars and bookmarks, 48×48 for Windows desktop shortcuts, and 256×256 for high-DPI displays and Windows application icons. A multi-size ICO covers all cases.
How do I create an ICO file?
Online: favicon.io, realfavicongenerator.net. CLI: ImageMagick (convert icon.png icon.ico). Node.js: png-to-ico package. Most tools can combine multiple sizes into a single .ico file.
Can I use SVG as a favicon?
Yes, modern browsers support SVG favicons: <link rel="icon" type="image/svg+xml" href="/favicon.svg">. However, ICO is still needed as a fallback for older browsers and some bookmark managers.
