Generate favicons first to see the HTML code.
How to Use This Tool
Create perfect favicons for your website in just a few steps:
Click the "Select Image" button or drag and drop your image file onto the upload area. The tool supports PNG, JPG, and SVG formats.
For best results, use a square image (at least 512×512 pixels) with a transparent background if needed.
- Background Color: Set a color for transparent images
- Shape: Choose between square, rounded, or circular icons
- Dark Mode: Optionally create separate icons for dark/light mode
- File Name: Customize the prefix for generated files
Choose which formats and sizes you want to generate:
- .ICO: Traditional favicon format with multiple sizes
- PNG: Individual files for each size
- Apple Touch Icon: For iOS devices
- Android Icons: For Android devices and PWAs
- SVG: Vector format for modern browsers
Click the "Generate Favicons" button to create your icons. Once generated:
- Preview how they'll look in browser tabs
- Download all files as a ZIP archive
- Download individual formats
- Copy the HTML code to your clipboard
Best Practices
- Use simple, recognizable designs that work at small sizes
- Avoid thin lines and small text
- Test your favicon on different backgrounds
- Include multiple sizes for different devices
- Consider dark/light mode variations
Pro Tip: For Progressive Web Apps (PWAs), enable the "PWA Manifest" option to generate additional configuration.
About This Favicon Generator
This tool creates professional favicons for websites, progressive web apps, and mobile applications. All processing occurs locally in your browser — your images never leave your device. If you need to prepare your source image first, try our image resizer to ensure proper dimensions or use the background remover for transparent backgrounds.

How Image Processing Works
When you generate favicons, this tool performs several operations:
- Canvas-based resampling: Your image is resized using high-quality downscaling algorithms optimized for small icon sizes. For precise control over dimensions, you might also explore our dedicated image cropper tool before generating favicons.
- Format conversion: Images are converted to appropriate formats (ICO, PNG, SVG) while maintaining visual integrity
- Smart cropping: Square images are centered; non-square images are proportionally scaled to fit
- Color preservation: Transparency and color accuracy are maintained across conversions
Format & Quality Considerations
Supported Formats
- ICO: Traditional Windows icon format containing multiple sizes (16×16 to 256×256). Best browser compatibility.
- PNG: Lossless compression with transparency support. Ideal for web and mobile icons. For additional PNG optimization, check our image compressor.
- SVG: Vector format that scales perfectly but has limited browser support for favicons.
Quality Guidelines
- Source image quality: Start with at least 512×512 pixels for optimal downscaling
- Compression: PNG compression reduces file size without visible quality loss
- Small icon clarity: Test 16×16 and 32×32 sizes for readability
- File size optimization: Typical favicons should be under 10KB for web performance
Privacy & Security
This tool prioritizes your privacy and security:
- Local processing only: All image operations occur in your browser using HTML5 Canvas
- No server uploads: Your images never leave your computer
- No tracking: No analytics or tracking of your uploaded images
- Offline capability: Once loaded, the tool can function without internet connection
- Data deletion: Generated files are temporary and removed when you close the page
Trust & Transparency: This tool uses open-source libraries (html2canvas, JSZip) and operates entirely client-side. You maintain full control of your images.
Best Practices & Common Issues
For Best Results
- Use square source images (1:1 aspect ratio) to avoid unexpected cropping
- Start with high-resolution images (512×512px minimum) for crisp small icons
- Use simple, bold designs that remain recognizable at 16×16 pixels
- Test icons on both light and dark backgrounds
- Include both ICO and PNG formats for maximum browser compatibility
Common Issues & Solutions
- Blurry small icons: Ensure source image has clean edges and adequate contrast. You might also try the image sharpener to enhance details before conversion.
- Transparency problems: Use PNG source with proper alpha channel
- Large file sizes: Enable compression and avoid unnecessary sizes
- Browser caching: Clear browser cache when testing new favicons
Frequently Asked Questions
Different devices and contexts use different icon sizes: browser tabs (16×16), bookmarks (32×32), mobile devices (180×180), and progressive web apps (192×192, 512×512). Providing multiple sizes ensures your icon looks crisp everywhere. For generating thumbnails from your favicon, try our thumbnail generator.
PNG compression uses lossless algorithms, meaning no visual quality is lost. File size reduction comes from optimized encoding and removal of metadata. For typical favicons (small, limited colors), compression can reduce file size by 20-40% without any visible difference.
ICO files are Windows icon containers that can hold multiple sizes in one file, offering excellent browser compatibility. PNG files offer better transparency support and are standard for web/mobile icons. Modern best practice is to provide both: ICO for legacy browsers, PNG for modern ones. If you need to extract the ICO file later, our image converter can help with format changes.
