How to make a favicon
- Select Choose file and pick a square-ish logo or icon. PNG, SVG, JPG and WebP all work. Large images give the best results.
- The tool draws every size you need and builds a ZIP.
- Select Download and unzip the folder into the root of your website.
- Paste the lines from
README.txtinto the<head>of your pages.
What is in the ZIP
favicon.ico: a multi-size file with 16, 32 and 48 pixel icons for browsers and Windows.favicon-16x16.pngandfavicon-32x32.png: crisp tab icons for modern browsers.apple-touch-icon.png: 180 × 180 pixels for iPhone and iPad home screens.icon-192.pngandicon-512.png: sizes for Android and web app manifests.README.txt: the exact HTML tags to copy.
Design tips
Favicons are tiny, usually 16 pixels wide in a tab. Use a simple shape with strong contrast, and avoid thin lines and small text. A single letter or symbol on a solid color works well. Images that are not square are centered inside a transparent square rather than stretched. If the artwork touches the edges, add a little padding first with the image resizer or trim it with the crop tool.
The ICO file stores each size as a PNG, which every current browser and operating system reads. Apple icons do not support transparency well: iOS fills it with black, so give your 180 pixel icon a solid background if you can.
Tips
- Starting from a vector? Export it with SVG to PNG at 4× first for a sharper source.
- Test the icon in a few tabs and in a dark theme.
- Browsers cache favicons for a long time. If you replace one, clear the cache or rename the file.
The icons are made in your browser, and your logo is never uploaded.
