Is this a real .ICO file or just a renamed PNG?

ToolKB builds a true binary Windows Icon format (.ICO) with genuine ICONDIR header structures containing multiple embedded resolution entries (16×16, 32×32, 48×48). It is fully compatible with legacy Internet Explorer, modern Chrome, and Windows shortcuts.

What image format should I upload for best results?

Upload a clean, high-resolution square PNG or SVG with a transparent background, preferably at least 512×512 pixels. ToolKB uses bicubic downsampling to preserve sharp edges at tiny 16×16 sizes.

Where do I place the downloaded favicon files in my website project?

Place the extracted files (favicon.ico, apple-touch-icon.png, site.webmanifest, etc.) directly in your website's root public directory (e.g. /public in Next.js/Vite or root folder in Apache/Nginx), and paste the provided HTML snippet inside the tags.
