Which Icon Sizes Do You Need?

🌐 Web / Favicon

16×16 — Classic browser tab favicon. Required for all websites. Displayed in browser tabs, bookmarks, and history.

32×32 — Higher-DPI browser tabs and bookmark bars. Recommended as a minimum for modern displays.

48×48 — Windows taskbar pinning and desktop shortcuts from browsers. Often used by CMS platforms like WordPress.

💡 Tip: Select 16 + 32 + 48 together for a complete favicon package. Modern browsers will pick the best size automatically.
