Tips
- Start from a square image of at least 512×512. Favicons are scaled down, never up, so anything smaller will look soft.
- Detailed logos turn to mush at 16×16. Many brands use a simplified mark — a single letter or symbol — at the smallest sizes.
- Maskable icons get cropped to a circle or squircle by Android. Keep important detail inside the middle 80%.
- Browsers cache favicons aggressively. Add ?v=2 to the path when you change one.
Frequently asked questions
Is my image uploaded anywhere?
No. The resizing happens on a canvas inside your browser using the standard Canvas API. The file never leaves your device.
Do I still need favicon.ico?
Only for Internet Explorer and some feed readers. Every current browser prefers PNG or SVG, and a single SVG favicon scales to all sizes.
