Question 1

What is a favicon?

Accepted Answer

A favicon is the small icon browsers display in tabs, bookmarks, and the address bar, and that operating systems use for shortcuts and pinned sites. Most websites ship a favicon.ico so every browser and OS picks the right icon.

Question 2

Why do I get both an .ico and PNG files?

Accepted Answer

The .ico download is a single 64×64 file, which classic browsers and desktop shortcuts rely on. Modern browsers prefer individual PNG favicons loaded via <link> tags, so the ZIP pack includes PNGs at 16, 32, 64, 128, and 256px. Shipping both covers every case.

Question 3

Why is the .ico only 64×64?

Accepted Answer

64×64 is the most widely used single favicon size - Windows desktop shortcuts, classic browsers, and many bookmarking systems all read it. When you need pixel-perfect icons at other sizes, the ZIP pack has individual PNGs at 16, 32, 64, 128, and 256px that you can link directly.

Question 4

Does it work in all browsers?

Accepted Answer

Yes. A 64×64 .ico works in every browser, and modern browsers additionally support PNG favicons via <link rel="icon" type="image/png">. Deploying both is the safest option.

Question 5

Are my images uploaded to a server?

Accepted Answer

No. All cropping, scaling, and encoding happens locally in your browser. Your image never leaves your device.
