Frequently Asked Questions

What is a multi-resolution favicon.ico?

A multi-resolution .ico file contains multiple image sizes (such as 16×16, 32×32, and 48×48 pixels) stored inside a single file. Modern browsers automatically display the 16×16 version on standard tabs and the 32×32 or 48×48 version on high-DPI Retina screens and desktop bookmarks.

How do I add the favicon to my website?

Download favicon.ico, place it in the public root folder of your website, and paste the generated <link rel="icon" href="/favicon.ico"> tag inside your HTML <head> section.

Does this tool support transparent backgrounds?

Yes! If you upload a transparent PNG or SVG, transparency is preserved across all generated icon resolutions by default.

Why should I include an Apple Touch Icon?

When iPhone or iPad users bookmark your website or add it to their home screen, iOS looks for an apple-touch-icon.png (180×180 px) to display as the app icon.

Are my brand logos uploaded to any server?

No. All icon generation, scaling, and binary encoding happen 100% locally in your web browser memory. Your assets never leave your device.
