Favicon Generator

The favicon is the smallest piece of branding a website has and the one users see most often. It sits in the browser tab, in the bookmark list, in history results and on a phone home screen when someone saves the site. A missing favicon leaves a generic grey placeholder that makes an otherwise professional site look unfinished.

The complication is that modern platforms want several sizes. A tab icon is tiny, an Android home screen icon is much larger, and Apple devices request their own touch icon. Producing each one by hand in an image editor is fiddly, and getting a design to survive being scaled to sixteen pixels square requires deliberate simplification rather than a shrunken logo.

This generator takes a source image and produces the icon files a site needs. Design for the smallest size first: a single letter, a simple mark or a bold shape reads clearly at tab size, while detailed illustrations and fine text turn into unreadable mush. Strong contrast against both light and dark browser themes helps too.

How to use the Favicon Generator

1. Prepare a square source image, ideally 512 by 512 pixels or larger.
2. Upload it to the generator.
3. Review the previews at each size, paying particular attention to the smallest.
4. Download the generated icon files.
5. Place them in your site root and add the matching link tags to your HTML head.

Examples

• A developer launching a new site generates the full icon set from a single logo file.
• A business rebranding replaces an outdated favicon across tab, bookmark and home screen contexts.
• A side project owner turns a simple monogram into a clean icon that reads well in a crowded tab bar.

Frequently asked questions

What size should my source image be?

A square image of at least 512 by 512 pixels gives the generator enough detail to scale down cleanly to every required size.

Why does my logo look blurry as a favicon?

Detailed artwork does not survive being reduced to sixteen pixels. Simplify to a single letter or bold shape for the smallest sizes.

Where do the files go?

Usually the root of your site, referenced by link tags in the head of every page. Many platforms have a settings field that handles this for you.

Why has the old icon not changed?

Browsers cache favicons aggressively. Force a refresh or clear the cache to see the update.
