New Free Tool: Favicon Generator & ICO Creator (All Sizes, SVG Support, 100% Browser-Based)

#css #webdev #frontend #productivity

Favicons are tiny, but getting them right is surprisingly annoying.

Different browsers and platforms want different sizes, some still expect a favicon.ico, and modern setups often use multiple PNG icons as well. If you’ve ever stitched those together manually, you know it’s easy to get wrong or just skip entirely.

To make this painless, I’ve added a new tool to FrontendTools.tech:

👉 Favicon Generator

https://www.frontendtools.tech/tools/favicon-generator

What the Favicon Generator does

The Favicon Generator takes a single image and produces a complete favicon pack for your site or app.

  • Multiple favicon sizes in one go

    • 16×16 (classic browser tab icon)
    • 32×32 (high-DPI)
    • 48×48, 64×64, 128×128, 256×256 (taskbar, app icons, touch icons, etc.)

  • ICO file creation

    • Generates a proper favicon.ico containing multiple embedded sizes (e.g. 16×16, 32×32, 48×48) for maximum browser compatibility.

  • Multiple input formats

    • Upload PNG, JPG, WebP, or SVG
    • SVG is rendered to canvas before generating PNG/ICO, so you can start from your vector logo.

  • Customization options

    • Background color for transparent logos
    • Padding slider to inset your icon inside the square
    • Corner radius slider for rounded or squircle-style favicons

  • One-click download

    • Download a ZIP pack containing:
    • favicon.ico
    • favicon-16x16.png
    • favicon-32x32.png
    • favicon-48x48.png
    • favicon-64x64.png
    • favicon-128x128.png
    • favicon-256x256.png

Privacy & performance

Like the other tools on FrontendTools.tech:

  • 100% client-side – all processing happens in your browser
  • No file uploads – images never leave your device
  • No login – just open the page and use it

Under the hood it uses a canvas to render each size, converts rasters/SVGs to PNG, then bundles selected sizes into a valid ICO file and a ZIP archive — all directly in the browser.

How to use it (step by step)

  1. Open the tool

Go to:

https://www.frontendtools.tech/tools/favicon-generator

  1. Upload your image
  • Drag & drop your logo/image file into the upload area, or
  • Click to browse and choose a PNG, JPG, WebP, or SVG.
  1. Pick your favicon sizes
  • Select the sizes you need: 16×16, 32×32, 48×48, 64×64, 128×128, 256×256.
  • For a typical website, 16×16, 32×32, and 48×48 already cover most cases.
  • For PWAs or apps, you’ll probably want the larger sizes as well.
  1. Customize appearance (optional)
  • Background color: choose a hex color for transparent logos.
  • Padding: add some breathing room so the icon isn’t flush with the edges.
  • Corner radius: round the corners for a softer, app-icon-like look.
  1. Generate favicons

Click “Generate Favicons”. The tool will:

  • Render your image at each selected size
  • Produce PNGs for each size
  • Create a multi-size favicon.ico
  1. Download the favicon pack
  • Click “Download All as ZIP” to get:
    • favicon.ico
    • All selected PNG files
  • You can also download individual sizes if you prefer.

How to wire it into your project

Once you’ve downloaded the ZIP:

  1. Place the files

A common setup:

  • Put favicon.ico in your web root
  • Put PNGs in your static assets (e.g. /public in Next.js or similar)
  1. Add link tags in your HTML <head>
