What sizes are inside the .ico?

Three: 16×16 (browser tabs), 32×32 (taskbar and bookmarks) and 48×48 (desktop shortcuts and tiles). Browsers pick the size they need from the single file.

Is transparency kept?

Yes. If your source image has transparency (for example a PNG logo), the transparent areas stay transparent in every size inside the .ico.

My image isn't square — what happens?

The tool center-crops it to a square first, then scales that square down to each favicon size. The middle of your image always survives; if the important part is off-center, crop the image to a square before uploading.

Where do I put the file?

Save it in your website's root folder named exactly favicon.ico. Most browsers find and use it automatically. If it doesn't show, add a tag inside your page's and clear your browser cache — favicons are cached aggressively.

PNG, JPG or WebP — square works best

Your favicon.ico is ready — one file containing 16×16, 32×32 and 48×48 versions, so browsers pick the size they need.

How to use it

Choose an image. A PNG, JPG or WebP — a square logo works best; anything else is center-cropped to a square.

Generate. The tool builds a genuine multi-size .ico file (16×16, 32×32, 48×48) right in your browser.

Download and install. Save it as favicon.ico in your website's root folder — browsers pick it up automatically.

Why generate a favicon.ico?

A favicon is the tiny icon browsers show in tabs, bookmarks and history next to your site's name. A proper .ico file packs several sizes — 16×16 for tabs, 32×32 for taskbars and 48×48 for desktop shortcuts — so every browser renders a crisp icon, even older ones. PNG favicons work in modern browsers through a <link rel="icon"> tag, but a classic multi-size favicon.ico in your site root remains the safest, most compatible choice, because browsers have fetched it automatically for decades. This generator builds a genuine .ico file locally — your image never leaves your device.
