An .ico file is a container format that holds multiple image resolutions (typically 16x16, 32x32, and 48x48 pixels) inside a single file, allowing the browser to select the ideal scale automatically.

Does this generator support PNG favicons?

Yes, we bundle standard PNG favicon formats in addition to standard .ico format so you have modern high-DPI assets.

Are my favicon assets safe?

Completely. All conversion is executed in-browser using standard Canvas render engines, keeping your brand assets fully private.

Should I upload a square image?

For best results, upload a square image. If you upload a rectangular image, the tool automatically crops it to the center to prevent distortion.

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.
