What Is Favicon Generator?

A favicon generator creates website icons in multiple standard sizes from a single source image. Favicons appear in browser tabs, bookmarks, home screens, and search results. Different contexts require different sizes: 16x16 for browser tabs, 32x32 for taskbars, 48x48 for Windows shortcuts, 192x192 for Android home screens, and 512x512 for PWA splash screens. This tool takes your source image and resizes it to all the sizes you select, producing crisp PNG favicon files for each.

Technical Guide

The favicon generator uses Canvas API drawImage to resize the source image to each selected target size. The source image is loaded into an Image element, then drawn onto a canvas set to each target dimension. For small sizes (16x16, 32x32), the browser applies its default interpolation algorithm. Each size is exported as PNG using canvas.toDataURL. For best results, start with a square source image at 512x512 or larger.

Tips & Best Practices

1
Start with a square image at least 512x512 pixels for best quality
2
Simple, bold designs work best at small favicon sizes
3
The 16x16 and 32x32 sizes are essential — others are optional
4
For PWA apps, include 192x192 and 512x512 in your manifest
