What Is a Favicon?
A favicon (short for favorite icon) is the small icon displayed in browser tabs, bookmarks, and mobile home screens for your website. Modern browsers and devices expect multiple sizes ranging from 16x16 pixels for browser tabs to 512x512 for PWA splash screens. This tool generates all common sizes from a single source image along with the HTML and web manifest code you need.
How to Generate Favicons
- Upload a source image (PNG, JPG, or SVG). Square images work best.
- Adjust background color, padding, and border radius to customize the output.
- Preview all generated sizes from 16x16 to 512x512.
- Download individual sizes or click Download All to get every favicon at once.
- Copy the HTML and manifest snippets into your project.
