What is a Favicon?

A Favicon Generator creates the small icon that appears in a browser tab next to your website's title — one of the most frequently seen but easiest to overlook pieces of a site's branding. Because favicons are displayed so small, intricate logos and detailed designs rarely work well; a bold, simple design using a single letter or initial on a solid background tends to stay legible and recognisable even at 16×16 pixels.

This generator lets you create exactly that kind of favicon — a letter on a coloured shape — in any size you need, from the standard 16×16 browser tab size up to 512×512 for Progressive Web App manifests. It pairs well with the Avatar Generator for a consistent visual style across your site's branding and user-facing avatars.

How to use this Favicon calculator

  1. Enter a Letter / Symbol — typically your brand's first initial.
  2. Set the Background Colour and Text Colour using hex codes (e.g. #2F6FED).
  3. Choose a Shape — Rounded Square, Square, or Circle.
  4. Select the Size you need — 32×32 for a standard favicon, or 192×192 / 512×512 for app icons.
  5. Review the live preview to confirm it's legible and on-brand.
  6. Click Download PNG and add the file to your website's favicon setup.

Formula & Methodology

The generator draws directly onto an HTML canvas at your chosen pixel size: a background shape filled with your chosen colour, followed by your letter or symbol centred on top in a bold, large font sized proportionally to the canvas.

Example: entering "T" with background #2F6FED, text colour #FFFFFF, Rounded Square shape, and size 32 produces a 32×32 pixel PNG with a blue rounded square background and a bold white "T" centred on top — ready to use as favicon.png.

Frequently Asked Questions

A favicon (short for 'favourite icon') is the small icon displayed in a browser tab, bookmarks bar, and history next to a website's title. It's one of the smallest but most frequently seen pieces of a website's branding, since it appears every time someone has the site open.
Browsers commonly display favicons at 16×16 or 32×32 pixels in the tab itself, but it's worth generating larger sizes too — 192×192 for Android home screen icons and 512×512 for Progressive Web App (PWA) manifests — so your site looks sharp across all these contexts.
Detailed designs lose clarity when scaled down to 16×16 pixels, which is why simple, bold designs — like a single letter or basic shape — tend to work much better as favicons than intricate logos. This generator's letter-based approach is designed specifically to stay legible even at the smallest favicon size.
Save the downloaded PNG as favicon.png (or convert it to .ico if your setup requires that specific format), place it in your site's root or public folder, and reference it in your HTML's <head> with a tag like <link rel="icon" href="/favicon.png">.
Yes — you can enter up to two characters, though a single letter or initial typically reads more clearly at small favicon sizes than two characters competing for the same tiny space.
A favicon represents a website or brand and appears in browser tabs, while the [Avatar Generator](/avatar-generator/) creates a profile picture representing an individual person, typically shown in user interfaces like comment sections or team directories. Both use a similar letter-on-background visual approach but serve different purposes.
Not necessarily — for a simple, clean favicon using your brand's initial or symbol and colour, a generator like this one can produce a usable result in seconds. More elaborate or detailed favicon designs (using a custom logo mark) would benefit from a designer's input.
Using your brand's primary colour as the background, with a high-contrast text colour (commonly white or black) for the letter, ensures the favicon stays legible and recognisable at a glance — which is all a favicon really needs to do, given how small and briefly viewed it typically is.
No — the favicon is generated entirely in your browser using the HTML canvas API. None of your inputs are sent to a server or stored.
Many sites use a single favicon.png referenced at multiple sizes via different <link> tags, but for the best results across browsers, bookmarks, Android home screens, and PWA installs, generating a few key sizes (32px, 192px, and 512px) covers most real-world use cases.
