What is Markdown Anchor Generator?
The Markdown Anchor Generator parses Markdown headings and creates anchor links for each one. It converts heading text to URL-safe slugs (lowercase, hyphens, no special characters) and generates the corresponding anchor link syntax. This is useful for creating table of contents or cross-references within a Markdown document. All processing happens in the browser.

Is my content sent to a server?
No. All processing happens in your browser. Nothing is transmitted.
