What is Favicon Generator?
Favicon Generator is a free online tool that creates all the favicon sizes your website needs from a single source image. Favicons are the small icons displayed in browser tabs, bookmarks, mobile home screens, and PWA splash screens. Modern web development requires multiple sizes to ensure your icon looks sharp across every device and platform, from 16x16 pixels for classic browser tabs to 512x512 for Progressive Web App splash screens. This tool generates all six standard sizes instantly using the browser Canvas API, with no server uploads required.
How to Use This Tool
Upload a source image by dragging it into the drop zone or clicking to browse your files. The tool accepts PNG, JPEG, SVG, and WebP formats. For best results, use a square image at least 512x512 pixels. Review the source image preview showing file details and dimensions. Click "Generate Favicons" to create all six sizes. Preview each generated icon, download them individually, or use "Download All" to grab the complete set. The tool also provides ready-to-use HTML link tags you can paste into your page head.
Common Use Cases
- Creating a complete favicon set when launching a new website or web application
- Generating Apple Touch Icons and Android Chrome icons for mobile compatibility
- Updating favicons across all sizes when rebranding or refreshing a site design
- Producing PWA icons for manifest.json with correct dimensions for splash screens
Why Use a Client-Side Tool?
All image processing happens directly in your browser using the HTML5 Canvas API. Your source images are never uploaded to any server, keeping unreleased logos and brand assets completely private. There are no file size limits, no watermarks, and no account required. The generated PNG files are universally supported across all browsers and platforms.
Frequently Asked Questions
What image format should I use as the source?
A square PNG image at 512x512 pixels or larger gives the best results. SVG files also work well since they scale without quality loss. JPEG and WebP are supported but may introduce compression artifacts at smaller sizes. Always start with the highest resolution available.
What happens if my source image is not square?
Non-square images will be stretched to fit the square favicon dimensions, which may distort the appearance. The tool warns you when it detects a non-square source. For best results, crop your image to a 1:1 aspect ratio before uploading.
Do I need all six favicon sizes?
For basic browser tab support, 16x16 and 32x32 are sufficient. However, including all sizes ensures your icon looks crisp on Apple devices (180x180), Android home screens (192x192), and PWA splash screens (512x512). The complete set provides the best cross-platform experience.
