What is Favicon Generator?

Favicon Generator creates complete multi-resolution favicon asset bundles from any uploaded logo or image. It outputs crisp 16x16, 32x32 browser tab icons, 180x180 Apple Touch Icons, and 192x192 / 512x512 Android PWA icons, complete with manifest.json and HTML code.

Zero-Server Client-Side Guarantee

Unlike legacy online utilities that upload sensitive media and documents to remote cloud storage, Shadow Toolkit executes this entire operation directly within your browser's local runtime. Your raw data never crosses the network.
