A square image works best (logo or icon)
Build a proper favicon.ico from any image — the little icon shown in browser tabs, bookmarks, and history. Instead of a single size, this bundles several square sizes into one .ico so each context can pick the one that fits. It all runs in your browser; your image is never uploaded.
Why one file holds several sizes
Browsers show favicons at different pixel sizes depending on where they appear. A multi-size .ico lets each place grab the best-fitting image, so the icon stays sharp everywhere instead of a single size being scaled up (blurry) or down (muddy).
For the crispest result, feed it a simple, square, high-contrast image. At 16×16 there's almost no room for detail, so a bold mark or single letter reads far better than a busy photo or fine text.
Common favicon sizes and where they show up
| Size | Where it's used |
|---|---|
| 16×16 | Browser tab and address bar |
| 32×32 | Taskbar shortcuts, higher-DPI tabs |
| 48×48 | Windows site shortcuts |
| 64×64 | Retina / high-DPI displays |
Bundling these into one favicon.ico covers the everyday cases without needing separate files.
How to use it
- Select or drop the image you want as your favicon — square works best.
- The browser resizes it to the standard sizes and bundles them into one .ico.
- Download favicon.ico and place it in your site's root directory.
Frequently asked questions
- Where do I put favicon.ico?
- In your website's root. Most browsers automatically look for /favicon.ico; you can also reference it explicitly with a <link rel="icon"> tag in your HTML.
- Does it keep transparency?
- Yes — a transparent background is preserved, so the favicon sits cleanly in the tab rather than inside a solid coloured square.
- Is my image uploaded to a server?
- No — the favicon is generated entirely in your browser.
