What is the Free Favicon Generator?
The Favicon Generator is an essential tool for developers and website creators. It allows you to transform any standard square image into a multi-resolution .ico icon format. Our generator packages multiple resolutions—specifically 16x16, 32x32, and 48x48 pixels—into a single .ico file, ensuring that your website's shortcut icon displays crisply across all legacy and modern browsers, tab bars, and bookmark folders.
100% Private, Client-Side Processing
All icon creation happens locally. Your brand assets, logo drawings, and designs never leave your local device. The generator resizes and packages the image layers inside your browser's memory using local canvas rendering. If you are designing templates or testing landing pages and need to document your work, the Supashot Chrome Extension lets you capture and annotate screenshots of your tab designs and favicon placements instantly in a local, secure workflow.
