How to Create Favicons From Images
Favicons are the small icons that appear in browser tabs and bookmarks. Learn how to create a complete favicon set from a single source image.
Key Takeaways
- A complete favicon implementation in 2025 requires multiple files: a 32×32 ICO for legacy browsers, an SVG for modern browsers, a 180×180 PNG for Apple devices, and 192×192 and 512×512 PNGs for Android and PWA.
- Start with a square image at least 512×512 pixels.
- Favicons must be instantly recognizable at tiny sizes.
- <link rel="icon" href="/favicon.ico" sizes="32x32">
- Test favicons across browsers (Chrome, Firefox, Safari, Edge), devices (desktop, tablet, phone), and contexts (tabs, bookmarks, home screen, PWA launcher).

The Modern Favicon Set
A complete favicon implementation in 2025 requires multiple files: a 32×32 ICO for legacy browsers, an SVG for modern browsers, a 180×180 PNG for Apple devices, and 192×192 and 512×512 PNGs for Android and PWA.
Starting Image Requirements
Start with a square image at least 512×512 pixels. SVG is ideal as a source because it scales without quality loss. If starting from a raster image, ensure it's clean and recognizable at very small sizes (16×16 pixels).
Design Considerations
Favicons must be instantly recognizable at tiny sizes. Simplify complex logos by removing text and fine details. Use bold shapes, high contrast, and limited colors. A single letter or simple icon works best.

Testing
Test favicons across browsers (Chrome, Firefox, Safari, Edge), devices (desktop, tablet, phone), and contexts (tabs, bookmarks, home screen, PWA launcher).
