Frequently Asked Questions
What sizes are included in the generated favicon.ico file?
The generated .ico container packages three multi-resolution PNG frames: 16x16 (for standard browser tabs), 32x32 (for Retina and high-DPI displays), and 48x48 (for desktop shortcuts and browser bookmark menus).
Why do I need both favicon.ico and PNG favicons?
While modern browsers support PNG favicons (favicon-32x32.png), legacy browsers, search engine indexers, and Windows operating system utilities still look specifically for /favicon.ico in the root directory. Our generator provides both formats for complete universal compatibility.
What is the Apple Touch Icon used for?
The Apple Touch Icon (180x180) is used when iOS Safari users choose "Add to Home Screen" on an iPhone or iPad, providing a sharp app-style icon on the user's home screen.
Is my uploaded logo or image sent to an external server?
No. 100% of the canvas rasterization, resizing, and binary .ico file construction occurs locally within your web browser. Your private brand assets, logos, and images never leave your device.
