How to Make a Favicon (PNG to ICO)
A favicon is the little icon in a browser tab. The classic way to make one is to convert a square PNG into an ICO file — and the image converter builds a proper multi-size favicon for you, free and in your browser.
Quick steps: make a square PNG of your logo → open the converter → choose ICO → Convert → Download → save it as favicon.ico.
Step 1 — Start with a square image
Favicons are square, so begin with a square PNG — ideally at least 256×256 pixels — with your logo or mark centered. Simple, high-contrast designs read best at tiny sizes.
Step 2 — Convert PNG to ICO
- Open the image converter.
- Drop in your square PNG.
- Choose ICO as the output format.
- Click Convert, then Download.
The converter produces a multi-resolution ICO containing 16, 32, 48, and 256-pixel versions — so browsers always have a crisp size to show.
Step 3 — Add it to your website
Rename the file favicon.ico and upload it to your site's root folder. Most browsers will find it automatically. To be explicit, add this line inside your page's <head>:
| Add to your <head> |
|---|
| <link rel="icon" href="/favicon.ico" sizes="any"> |
Common questions
What size should a favicon be?
A good favicon includes 16×16, 32×32, and 48×48, plus 256×256 for high-resolution screens. A multi-size ICO holds them all in one file — which is exactly what the converter creates.
Can I use a PNG as a favicon instead?
Modern browsers do accept PNG favicons, but a multi-size ICO is the most widely compatible option and still the standard for favicon.ico.
Make your favicon now: open the converter, drop in a square PNG, and choose ICO.
