How to Create a Favicon for Your Website
A favicon is a small thing with a big impact. It appears in browser tabs, bookmarks, search results, home screen shortcuts and browser history. A missing or blurry favicon signals an unfinished website. A clean, recognizable one reinforces your brand every time someone switches tabs.
This guide covers what a favicon is, why it matters, the sizes you need, the PNG vs ICO debate, and how to create one using the free Favicon Generator in under two minutes.
What is a favicon?
The word "favicon" comes from "favorite icon" — it was originally the icon shown when you bookmarked a page in Internet Explorer. Today it appears in:
- Browser tabs (the tiny icon next to the page title)
- Bookmarks and reading lists
- Browser history
- Search engine results (some engines show it next to the URL)
- Home screen shortcuts on iOS and Android
- Progressive Web App (PWA) icons
Why favicons matter for branding
Most users have 10–20 tabs open at once. A recognizable favicon is how they find your site again without reading the full title. It is also a trust signal — a site without a favicon looks unfinished or abandoned.
A favicon is the smallest piece of your brand identity. It shows up everywhere your URL does.
Recommended favicon sizes
- 16×16px — Standard browser tab icon
- 32×32px — High-DPI browser tabs, taskbar shortcuts
- 48×48px — Windows site icons
- 180×180px — Apple touch icon (iOS home screen)
- 512×512px — PWA manifest, Android home screen
At minimum, create a 32×32 PNG for browser tabs and a 180×180 PNG for Apple touch icons. The Favicon Generator lets you export any of these sizes with one click.
PNG favicon vs ICO favicon
The original favicon format was ICO, a Windows icon container that can hold multiple sizes in one file. For years, browsers required an ICO file at the root of the domain (/favicon.ico).
Today, all modern browsers support PNG favicons declared with a <link> tag. PNG is simpler to create, easier to optimize, and works everywhere that matters. The only reason to still provide a /favicon.ico is for very old browsers and automated tools that request it by default.
The recommended approach in 2026: provide a PNG favicon via the HTML link tag, and optionally place a 32×32 ICO at /favicon.ico as a fallback.
The HTML snippet you need
Add these lines to the <head> of your HTML:
<link rel="icon" type="image/png" href="/favicon.png" />
<link rel="apple-touch-icon" href="/apple-touch-icon.png" />The Favicon Generator copies this snippet for you with one click.
How to use the Favicon Generator
- Open the Favicon Generator.
- Choose a mode: Text (a letter or initials), Emoji, or Image upload.
- Set your background color, text/icon color, and shape (square, rounded or circle).
- Select the export size you need (32×32 for browser tabs, 180×180 for Apple touch).
- Click Download PNG to save the file.
- Click Copy HTML snippet and paste it into your site's
<head>.
Common favicon mistakes to avoid
- Too much detail — At 16×16px, complex logos become unreadable. Use a single letter, symbol or simple shape.
- No contrast — A light icon on a white background disappears in browser tabs. Use strong contrast.
- Wrong size — Uploading a 16×16 image and expecting it to look good at 180×180 will result in a blurry icon. Generate each size separately.
- Forgetting the Apple touch icon — iOS users who add your site to their home screen will see a blank icon if you skip the 180×180 version.
- Not updating after a rebrand — Old favicons cached in browsers can confuse returning users after a brand refresh.
