How to use markdown previewer safely
Why Markdown helps utility sites
Markdown is a lightweight format for writing structured content without heavy editing tools. It is common in README files, docs, changelogs, issue comments, static-site content, and support notes.
For utility websites, Markdown is useful because it keeps guides easy to scan: headings create structure, lists group steps, links connect related resources, and code blocks make examples readable.
What this previewer supports
The previewer renders a practical subset of Markdown locally: headings, paragraphs, bullet lists, links, bold text, italic text, inline code, and fenced code blocks. It also counts words, lines, headings, and links.
Raw HTML is escaped before preview rendering, so pasted tags are displayed as text. This keeps the preview focused on drafting and prevents snippets from running as markup.
- Headings from # through ###
- Dash or asterisk bullet lists
- Markdown links to http, https, or site-relative URLs
- Bold, italic, and inline code
- Fenced code blocks for examples
Practical publishing workflow
Draft the outline, preview the structure, and fix headings or lists before publishing. For public guides, make sure the content answers a real user question and links naturally to relevant tools or policy pages.
For sensitive notes, redact secrets, email addresses, tokens, and personal data before sharing the final draft. Browser-only previewing keeps content local, but it cannot decide whether the draft is safe to publish.
