What is a Markdown badge and where can I use it?

A Markdown badge is a small image generated by shields.io that displays metadata like build status, npm version, or license type. You paste the Markdown snippet into any README.md, GitHub wiki, or documentation site that renders Markdown.

Does this badge generator work offline or need a server?

The badge builder runs entirely in your browser — no data is sent to any server. The preview fetches the badge image directly from shields.io, which is a free public service.

What badge styles are available?

Five styles are supported: flat (default), flat-square, for-the-badge (uppercase, bold), plastic (3D gradient), and social (rounded, for follower counts). All styles are generated via shields.io.

How do I add a logo to my badge?

Enter any Simple Icons slug (e.g. 'github', 'npm', 'typescript', 'react') in the Logo field. You can browse all available slugs at simpleicons.org. Leave blank for a text-only badge.

Can I use a custom color for my badge?

Yes. Enter any valid hex color (without the # prefix) or a named shields.io color like brightgreen, blue, red, orange, yellow, green, or lightgrey.

What is the shields.io URL format?

Shields.io uses the pattern: https://img.shields.io/badge/{label}-{message}-{color}?style={style}&logo={logo}. This tool builds that URL for you and provides ready-to-paste Markdown and HTML snippets.
