Frequently Asked Questions
What size should my favicon be?
Provide multiple sizes: 16x16 and 32x32 for browsers, 180x180 for Apple Touch Icon, and 192x192/512x512 for PWA. SVG favicons work at any size and are becoming standard.
What file format is best?
ICO format has widest browser support. PNG is modern and supports transparency. SVG is scalable and increasingly supported. Most sites use multiple formats.
Why does my favicon look blurry?
Likely using a low-resolution image that gets scaled up. Ensure your source image is at least 512x512 with a simple, bold design that remains recognizable at 16x16.
How do I test dark mode appearance?
This tool shows your favicon on both light and dark backgrounds. For true dark mode adaptation, use SVG with CSS media queries for prefers-color-scheme.
