About this tool
READMEs, changelogs and notes are written in Markdown, but reading the raw text is not the same as seeing the result. The Markdown Preview renders a document in your browser, headings, emphasis, links, images, code, lists, task lists, quotes and tables, into a clean page you can read in full screen, without any raw HTML being executed. Handy for checking a README before pushing it or reading a file someone sent you.

Key features of this tool
The syntax people use
Headings, bold, italic, strikethrough, inline code and fenced blocks, links, images, ordered and bullet lists, task lists, blockquotes, tables and rules.
Safe rendering
The preview is built from DOM nodes, never from raw HTML, so scripts or embedded HTML in a file cannot run; only http(s) links and images are honoured.
Stays in your browser
The text is rendered locally; nothing is uploaded or stored.
Frequently asked questions
Which Markdown flavour is this?
CommonMark basics with the GitHub extensions most people rely on: tables, task lists and strikethrough. Footnotes, math and raw HTML are not rendered.
Why is my HTML not showing?
Raw HTML is deliberately ignored for safety; the preview only renders Markdown constructs.
Can I export the HTML?
This tool is a viewer; copy the source with the action in the header or use a converter for HTML output.
Are my files or data uploaded?
No. The tool is plain JavaScript that runs in your browser; the files or data you provide here are never uploaded to our servers.
