What is Favicon Generator?

Favicon Generator takes a source image or emoji and exports a complete favicon package — all required PNG sizes plus .ico — so your site looks sharp in browser tabs, bookmarks, taskbars, and phone home screens.

A favicon is often the smallest piece of branding on a site, but it appears on every tab, bookmark, and shortcut. A blurry or missing favicon is a subtle but real trust signal.


Why You Need Multiple Sizes

16×16 / 32×32

Browser tab and address bar. The smallest sizes — your icon must read clearly even as a tiny square.

180×180

Apple touch icon — shows when a user adds your site to their iPhone or iPad home screen.

192×192 / 512×512

Android PWA icon — required for 'Add to home screen' on Android and Chrome's splash screen.

.ico File

Contains 16×16 and 32×32 in a single file. Required by some server tools and legacy browsers.


How to Use Favicon Generator

Upload your image

Drag-and-drop a PNG or SVG with a transparent background, or type any emoji into the emoji field.

Preview all sizes

See how your icon looks at 16×16, 32×32, and 180×180 in the live preview grid.

Download the package

Click 'Download' to get a ZIP containing all sizes as PNG files plus a favicon.ico.

Add to your HTML

Paste the provided <link> tags into your <head> to wire up all sizes correctly.


<link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png">
<link rel="icon" type="image/png" sizes="16x16" href="/favicon-16x16.png">
<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">

Tips & Common Mistakes

Design for 16×16 first. A logo that looks great at 512×512 can become unreadable at 16×16. If your logo has fine details, consider a simplified lettermark or icon for favicon use.

Avoid text in favicons. Even a short two-letter abbreviation becomes a blur at 16×16 on a standard display and is unreadable on retina screens at this scale.

Use a transparent or white background. Colored backgrounds look fine on light-mode tabs but can clash with dark-mode browser chrome. Transparent adapts to both.

Frequently Asked Questions

What sizes should a favicon package include?
At minimum: 16×16 and 32×32 for browser tabs. A complete package also includes 48×48 for taskbars, 180×180 for Apple touch icon, and 192×192 / 512×512 for Android PWA.
Can I use an emoji as a favicon?
Yes — the generator renders any emoji to a clean square icon at all required sizes. Emoji favicons are trendy and surprisingly professional on modern browsers.
What image format works best as input?
PNG with a transparent background is ideal. SVG works too. Avoid JPEG — the compression artifacts look bad at small sizes.
Do I need an .ico file?
Old IE required .ico files. Modern browsers (Chrome, Firefox, Safari, Edge) all support PNG favicons. The generator exports .ico for maximum compatibility.
