Favicon Generator
Upload an image and generate favicons in all required sizes (16x16, 32x32, 48x48, 180x180, etc.).
About the Favicon Generator
A favicon generator creates complete icon sets for modern web browsers, mobile operating systems, and bookmark menus from a single uploaded logo or image. Favicons enhance brand recognition and make browser tabs easy to spot among dozens of open tabs.
Modern web platforms require multiple icon resolutions: 16×16 and 32×32 pixels for desktop browser tabs, 48×48 for desktop shortcuts, 180×180 for Apple Touch Icons (iOS home screen bookmarks), and 192×192 / 512×512 PNGs for Progressive Web Apps (PWAs) and Android devices, alongside standard `favicon.ico` containers.
The generator automatically resizes, optimizes, and packages all necessary icon sizes into a ready-to-use zip file, complete with HTML `<link>` tags ready to paste into your website's `<head>` section.
Uploading a 512×512 PNG company logo generates crisp multi-resolution icons (16px, 32px, 48px, 180px, 192px, 512px) and a multi-layer `favicon.ico` file.
Tips for best results
- Use simple, bold silhouettes with high contrast; intricate details and fine text become illegible when downscaled to 16×16 pixels.
- Transparent background PNGs look best in browser tabs, blending seamlessly across both light and dark browser themes.
- Place `favicon.ico` in your website's root directory so older web crawlers and legacy browsers locate it automatically.
