Favicon App Icon Generator Tool - Complete Favicon Package with ICO PNG and PWA Icons
First Published:
Last Updated:
This tool generates a complete favicon and app icon package from a single source image or emoji. It creates all standard icon sizes for browsers, iOS, Android, and Windows, plus the HTML code, PWA manifest, and browserconfig.xml you need to implement them. Every icon is generated entirely in your browser using Canvas API — your images are never uploaded to any server.
Unlike most favicon generators that only produce a few sizes, this tool generates 48 icon files including multi-size ICO, all Apple Touch Icon variants, Android Chrome icons for every DPI, generic platform icons, Microsoft Tile images, and dedicated maskable icons for PWA, along with ready-to-use code snippets for complete cross-platform favicon implementation.
All processing is performed entirely in your browser using client-side JavaScript. No data is transmitted to any server. Your images never leave your device.
- This tool is provided "AS IS" without any warranties of any kind.
- The author accepts no responsibility for incorrect icon rendering or compatibility issues.
- For best results, use a square source image at least 512×512px.
- Generated ICO files contain embedded PNG data (supported by all modern browsers).
- Always test generated icons across different browsers and devices.
- By using this tool, you accept full responsibility for any outcomes.
This tool uses client-side JavaScript for all processing. No data is transmitted to servers, no files are uploaded online, all processing happens locally in your browser. Once loaded, this tool continues to work even without an internet connection. For more details, please refer to our Web Tools Disclaimer.

Generated Icon Sizes
- favicon.ico: Multi-size ICO containing 16×16, 32×32, and 48×48 (for maximum browser compatibility)
- Standard Favicons: 16×16, 32×32, 48×48 PNG
- Apple Touch Icons: 57, 60, 72, 76, 114, 120, 144, 152, 180px (all required iOS sizes, plus apple-touch-icon.png)
- Android Chrome: 36, 48, 72, 96, 128, 144, 152, 192, 256, 384, 512px PNG (all DPI variants for PWA & Add to Home Screen)

Important Notes
- For best quality, use a source image that is at least 512×512 pixels. Smaller images will be upscaled and may appear blurry at larger icon sizes.
- Square source images produce the best results. Non-square images are center-cropped to fit.
- The ICO file uses embedded PNG format, which is supported by all modern browsers (IE11+, Chrome, Firefox, Safari, Edge).
- Apple Touch Icons should ideally not have rounded corners or transparency — iOS applies its own mask. If you need rounded icons, use the "Square" shape for Apple icons.
- The generated site.webmanifest file contains placeholder values for "name" and "description" that you should customize.
- This tool works offline once the page is loaded — no internet connection is required for icon generation.
