What is a Favicon Generator?

A favicon generator is an online tool that converts your image into multiple favicon formats and sizes required for modern websites and applications. Our free favicon generator creates all the necessary icon sizes for browsers, mobile devices, and progressive web apps (PWA) - all processed securely in your browser.

Why Multiple Favicon Sizes?

Different platforms and devices require different favicon sizes for optimal display:

  • 16×16 and 32×32 - Classic browser tabs and bookmarks
  • 48×48 and 64×64 - Windows taskbar and desktop shortcuts
  • 128×128 - Chrome Web Store and browser extensions
  • 256×256 - High-resolution displays and Windows 8+ tiles
  • 512×512 - PWA splash screens and iOS home screen icons
  • 1024×1024 - High-resolution retina displays and future-proofing

Our tool generates all these sizes from a single source image, ensuring consistency across all platforms.

How to Create the Perfect Favicon

Best Source Image Requirements

  • Size: Minimum 512×512 pixels, recommended 1024×1024 or larger
  • Format: PNG with transparent background for best results
  • Design: Simple, recognizable design that works at small sizes
  • Colors: High contrast colors for visibility
  • Content: Avoid fine details that disappear at 16×16

Design Tips for Small Icons

Creating effective favicons requires special consideration for small sizes:

  • Use bold, simple shapes rather than complex illustrations
  • Limit text to 1-2 characters maximum
  • Ensure good contrast between icon and background
  • Test how your design looks at 16×16 pixels
  • Consider using your brand's primary color or logo mark

Frequently Asked Questions

What image formats can I upload?

You can upload images in JPG, PNG, GIF, WebP, and most other common image formats. PNG with transparency is recommended for best results.

What's the best size for the source image?

We recommend starting with at least 1024×1024 pixels to ensure high quality at all sizes. Larger source images produce better results when downscaling.

Do I need all these favicon sizes?

For comprehensive browser and device support, yes. However, you can select only the sizes you need. At minimum, include 16×16, 32×32, and 512×512 for broad compatibility.

Can I use a logo with text?

Yes, but keep text minimal. At small sizes (16×16), detailed text becomes illegible. Consider using just an icon or initial letter.

What's the difference between .ico and .png favicons?

.ico is the legacy favicon format that can contain multiple sizes in one file. Modern browsers support PNG favicons with better quality and transparency. We recommend using PNG format.

How do I create a transparent favicon?

Upload a PNG image with a transparent background. The tool preserves transparency in all generated sizes.

Will this work for WordPress sites?

Yes! Generate your favicons, download the ZIP, and upload the files to your WordPress site's root directory or use a favicon plugin.

Can I use this for mobile app icons?

Yes, the 512×512 and 1024×1024 sizes work well for mobile app icons and PWA splash screens.

Technical Details

This tool uses the HTML5 Canvas API for client-side image processing. Images are resized using high-quality bicubic interpolation to maintain clarity at all sizes. The generated PNG files use optimal compression while preserving transparency and color accuracy.
