Favicon Generator
About the Tool

A focused, client-side favicon engine

Favicon Generator is built to make modern website favicon creation fast, accurate, and completely private. Every asset is rendered and packaged directly inside your browser.

100% Client-Side Processing

Your source files, images, and text never leave your computer. All rasterization, SVG sanitization, multi-resolution scaling, and binary ZIP packaging happen entirely via native browser Canvas and JavaScript APIs.

🎯

Unified Rendering Pipeline

The exact same mathematical viewport and scaling engine drives both the real-time previews and the exported PNG and ICO binaries, ensuring what you see on screen is pixel-identical to your downloaded files.

📦

Real Multi-Resolution .ICO

We don't rename a single PNG to .ico. The generator constructs a genuine Windows ICO binary container containing embedded 16×16, 32×32, 48×48, and 64×64 streams with verified directory offsets.

📱

Complete Platform Standards

Generates assets for modern desktop browsers, Apple Touch Icons (180×180), Android Chrome PWA icons (192×192 & 512×512), and valid site.webmanifest configurations.
