Favicon Creation Guide

Favicon Basic Specifications

Favicon (Favorite Icon) is a website's icon displayed in browser tabs, bookmark bars, home screens on mobile devices, and other locations. The standard favicon is a 16x16 pixel ICO format file, but modern websites need multiple sizes to adapt to different devices and scenarios. Apple Touch Icons require 180x180 pixel PNG format, Android Chrome needs 192x192 and 512x512 pixels, and Windows tiles need 150x150 pixels.

When designing favicons, consider the minimalist principle - in the extremely small 16x16 pixel space, complex patterns become blurry and unclear. It is recommended to use simple geometric shapes, letters, or high-contrast colors. Avoid fine lines and small details, as these elements will disappear or become distorted at low resolution.

Creation Tools and Workflow

The standard workflow for creating favicons is: first create a larger source file (at least 512x512 pixels), then use tools to export various sizes. It is recommended to use vector design tools like Figma or Sketch for lossless scaling. For automated generation, the RealFaviconGenerator online tool can automatically generate all required sizes and configuration code.

PWA (Progressive Web Apps) have stricter requirements for favicons, requiring maskable format icons to ensure proper display under different shape masks. When creating maskable icons, place main visual elements in the central safe area (approximately 80% of the area) to prevent important information from being cropped.
