Frequently Asked Questions
What sizes should a favicon.ico contain?
For broad compatibility, include at least 16×16 and 32×32 pixels. For Windows taskbar and high-DPI displays, also include 48×48. Modern multi-icon favicon.ico files may include 16, 32, 48, and 64 pixel sizes.
Do I still need favicon.ico in 2024?
Yes, favicon.ico remains the most compatible format for browser favicons. While modern browsers support PNG favicons via <link> tags, many still look for /favicon.ico as a fallback. It is recommended to have both.
What is the difference between ICO and PNG favicons?
ICO can contain multiple sizes in one file and is universally supported. PNG favicons require separate files for each size and use <link> tags in HTML. Use ICO for the /favicon.ico fallback and PNG for specific sizes in your HTML head.
What sizes do I need for a PWA?
Progressive Web Apps require at minimum 192×192 and 512×512 PNG icons in the web manifest. For best results, also include 72, 96, 128, 144, 152, and 384 pixel sizes. Consider adding a maskable icon for Android adaptive icons.
How do I add a favicon to my website?
Place favicon.ico in your website root directory (browsers check /favicon.ico automatically). Additionally, add <link rel="icon" type="image/x-icon" href="/favicon.ico"> in your HTML <head> section.
