Markdown preview is most useful when you want to see how headings, lists, links, and code fences will look before they reach a CMS or documentation site. That makes it easier to spot awkward nesting, broken tables, or a heading level that jumps too far.
Use the preview to check structure, not just appearance. A post that looks neat in the editor can still have broken links, stray HTML, or missing alt text, so this tool works best as a quick editorial safety net before your final publish step.
Authors and developers use this page to sanity-check headings, lists, tables, and code blocks before pasting HTML into a CMS or static site generator.
It is a drafting aid, not a full documentation pipeline — always run your production build for final HTML.
Tables, fenced code blocks, and task lists render when the parser supports GFM extensions. Exotic plugins from your repo may differ.
The page parses Markdown with a lightweight library, then sanitizes HTML with DOMPurify to reduce script injection risk in your preview pane. It is still not a replacement for your CMS or static-site pipeline.
Your Markdown body stays in the browser; only the parser scripts are fetched from the CDN.
