Frequently Asked Questions
A favicon.ico is a small icon file used by web browsers to display in tabs, bookmarks, and history. The .ico format can contain multiple sizes in a single file, so the browser picks the best size for each context.
For most websites, 16x16 (browser tab), 32x32 (taskbar), and 48x48 (Windows desktop) are essential. Including 64x64, 128x128, and 256x256 provides better quality for high-DPI displays and larger icon contexts.
PNG with a transparent background works best. Square images produce the best results. If your image isn't square, it will be stretched to fit.
No. The entire favicon generation process runs in your browser using JavaScript. Your image never leaves your device.
Place the downloaded favicon.ico in your website's root directory. Add <link rel="icon" href="/favicon.ico"> to your HTML <head> section. Most browsers will also auto-detect favicon.ico at the root URL.
The .ico format is mainly for websites. For mobile app icons, you typically need separate PNG files at specific sizes. However, the preview images shown here can be right-clicked and saved individually as PNG files.
