Build the icon set your site can actually use
A favicon is not just one tiny ICO file. A modern site may need several PNG sizes, an Apple touch icon, PWA icons and a small block of HTML to connect them.
Start with a square source
A simple, high-contrast mark survives small sizes better than a detailed illustration. A square source around 512 pixels or larger gives the generator enough room to make smaller icons cleanly.
Preview the smallest icon before publishing it. A logo that looks perfect at 512 pixels can become unreadable at 16 or 32 pixels.
Check the package before replacing your current icons
Open the generated files, confirm the names and sizes, and paste the supplied markup into the head of the site. Keep your existing favicon set until the new files have been verified.
Frequently asked questions
What image should I use for a favicon?
A clean square logo or symbol works best. High contrast and simple shapes usually survive tiny icon sizes better than fine detail.
Which favicon sizes should a website have?
Common web and device workflows use several sizes rather than one file. The generator provides multiple PNG sizes and an ICO package so you can choose the files your site needs.
Do I need favicon.ico and PNG icons?
They serve different browser and platform workflows, so keeping both is practical when broad compatibility matters.
Can I use an SVG logo?
Yes when the browser workflow can decode it, but check the rendered PNG/ICO results because fonts, filters and external references can change during rasterization.
