PNG to ICO Converter — Multi-Size Favicon Generator
Create a browser-compatible .ico favicon from any PNG image. The ICO format supports multiple sizes embedded in a single file — browsers and operating systems pick the best size for each context: 16×16 for browser tabs, 32×32 for taskbar shortcuts, 48×48 for desktop icons, and 256×256 for high-DPI displays. This tool uses the PNG-in-ICO embedding format (supported since Windows Vista), which preserves full alpha transparency. Everything runs in your browser using the Canvas API — no upload, no server, completely free.
Private & free — this tool runs entirely in your browser.
