Markdown Tools

Sample images use inline data URIs so the demo works offline and avoids blockers. In your own Markdown, use any normal URL instead — e.g. ![alt](https://example.com/photo.jpg). Syntax highlighting and Mermaid diagrams load from bundled assets on first use — fully offline.

Pads columns so the | pipes line up in monospace — same data, easier to read in source.

Generates a linked table of contents from headings. Headings get anchor IDs when rendered — links use GitHub-style slugs.

Edit YAML front matter and body separately — common for static site generators and docs repos.

Lists every ![alt](url) and [text](url) in your document — external URLs work the same way; only the sample uses inline images.

Compare two Markdown versions line by line. Pull the current shared document into Original, then paste or edit Modified.
