Favicon Generator
A favicon generator is a specialized image utility that converts your logos or photos into the standard "favorite icon" formats required by modern web browsers. Favicons are the small icons that appear in browser tabs, bookmark bars, and mobile home screens, providing a crucial visual identity for your website. Our generator creates a comprehensive package of icons, including `.ico` files for legacy browsers and high-resolution `.png` files for Apple Touch and Android devices. Whether you are a brand designer or a solo developer, this tool ensures your site looks professional and recognizable across every platform.
How to Use Favicon Generator Step by Step
- Upload your "Master Image" — choose a high-quality square logo (PNG or JPG).
- Select "Output Sizes" — toggle support for 16x16, 32x32, and 180x180 (Apple) icons.
- Preview the "Browser Tab" — see how your icon will look in a simulated browser interface.
- Click "Generate Favicon" — the tool will rescale and format your image.
- Download the "Favicon Pack" — get a ZIP file containing all necessary files and the required HTML code.
- Install the Code — paste the provided `<link>` tags into the `<head>` of your website.
Favicon Generator Formula Explained
Ensuring the icon remains square (1:1) to prevent distortion.
Maintaining 32-bit transparency support for clean edges on dark/light tabs.
The generator uses advanced "Resampling" algorithms to shrink your image. Unlike simple scaling, which can make icons look blurry, Bilinear and Bicubic interpolation preserve edge sharpness. The resulting images are then "Packaged" into an `.ico` container—a special Microsoft format that can hold multiple sizes in a single file—allowing the browser to automatically pick the best size for its current display density.
Favicon Generator — Worked Examples
Example 1 — Brand Identity Setup

Example 2 — Mobile Home Screen Icon

Who Uses Favicon Generator?
Web Developers
Quickly generating the complex set of icon files and HTML tags needed for a new project launch.
Graphic Designers

E-commerce Owners
Improving brand recognition for their Shopify or WooCommerce store in a sea of open browser tabs.

Common Favicon Generator Mistakes to Avoid
Using a complex logo with text. At 16x16, text is unreadable. Use a simple, bold symbol instead.
Uploading a rectangular image, which leads to "stretching" or black bars on the sides of the icon.
Using a white background instead of a transparent PNG, which creates a white box on browsers with dark mode tabs.
