When to use Favicon Generator

You're wrapping up a side project and the browser tab still shows a blank sheet of paper — the one detail that signals 'unfinished' before anyone reads a word. Upload your logo or a single emoji and get back every size a browser actually needs: 16×16, 32×32, 48×48, and 180×180 for Apple touch icons, plus an ICO bundle you can drop straight into your project's `public/` folder. No design tool needed — Canvas renders the resized versions on your device, so the source image never leaves the browser. Useful for client handoffs where the logo file came as a 2000×2000 PNG, portfolio sites, and any project where you're handling the build but not the design assets.

  • Generate all favicon sizes from a client logo before a site launch
  • Turn a single emoji into a complete favicon set for a side project
  • Package an ICO bundle for a portfolio site from a high-res PNG logo

About this tool

Give your website or portfolio the one detail that signals "real project": a proper favicon. Upload a logo, an icon, or type a single emoji and get back every size browsers actually need — 16×16, 32×32, 48×48, and 180×180 for Apple touch icons — plus an ICO bundle you can drop straight into your project's public folder. Rendering happens on your device, so your source image never leaves the browser. Useful for side projects, client handoffs, and any time you're wrapping up a build and realize the browser tab still shows a blank sheet of paper.

Frequently asked

Is this favicon generator private? Do you upload my images?
No uploads. Canvas API renders each favicon size from your source image in this browser tab — the source file is never transmitted to any server, and the resizing happens without a network connection.
What sizes are generated?
16x16, 32x32, 48x48, and 180x180 (Apple touch icon). You can download each size individually as PNG or bundle them as an ICO file.
Can I generate a favicon from an emoji?
Yes. Type any emoji or text in the text input field and it will be rendered as a favicon at all sizes.
What is the ICO format?
ICO is a multi-resolution icon format used by browsers. It bundles multiple sizes into a single file so the browser can pick the best one.
