FAQ
- Why put several sizes in one file?
- ICO is built to hold multiple resolutions, and whatever displays the icon picks the one that fits. Browser tabs typically use 16px, bookmarks and shortcuts 32px, and Windows Explorer 48px. With only one size embedded, every other context has to stretch or shrink it, and it looks soft.
- Can I use a non-square image?
- You can. Since icons are square by convention, the image is centred inside the square at its original aspect ratio with the leftover space left transparent. Nothing is cropped, so your logo will not lose an edge. If the padding bothers you, crop to a square before uploading.
- How do I actually apply the favicon?
- Place the file at the root of your site named favicon.ico and most browsers will find it automatically. To be explicit, point at it with a link tag in your HTML head. If an old favicon refuses to change, it is usually browser cache — check with a hard refresh.
