Markdown Preview

The preview uses GitHub-flavored Markdown (GFM), the dialect used on GitHub, GitLab, and many documentation tools. On top of standard Markdown it supports pipe tables, task lists (- [x] done), strikethrough (~~old~~), fenced code blocks, and bare URLs that become links. Single line breaks inside a paragraph are not turned into <br>, which matches how README files render on GitHub.

The preview updates as you type, so it is a quick way to check a README, a release note, or a pull request description before posting it. Tables made with CSV to Markdown can be pasted here to see how they will look.

Markdown can contain raw HTML, and pasted content can include scripts or event handlers. Before display, the generated HTML is sanitized with DOMPurify, which removes <script> tags, onclick-style attributes, and javascript: links while keeping ordinary formatting. Links open in a new tab.

Copy HTML copies this sanitized HTML source. You can paste it into a CMS, an email template, or a static page that does not accept Markdown.

The print option opens the rendered document in a new tab with clean print styles: no site navigation, sensible margins, and table rows and code blocks kept together across page breaks where possible. It then opens the browser's print dialog, where you can choose Save as PDF. If nothing happens, allow pop-ups for this site and try again.
