About

About the Markdown Preview

Markdown Preview is a free, browser-based editor that renders your Markdown live as you type, showing the formatted result alongside the source. Reach for it when you want to draft a README, GitHub issue, documentation page, or release note and see exactly how the headings, lists, code blocks, and links will look before you ship them. Everything runs entirely in your browser, so your text never leaves your machine.

How to use the Markdown Preview

  1. 1Type or paste your Markdown into the editor pane.
  2. 2Watch the formatted output update live in the preview pane as you write.
  3. 3Use standard Markdown syntax: # for headings, ** for bold, - for lists, and fenced code blocks.
  4. 4Refine the source until the rendered preview matches what you want.
  5. 5Copy the finished Markdown into your README, docs, issue, or CMS.

Common use cases

  • Drafting a README or CONTRIBUTING file and checking the formatting before committing it
  • Previewing a GitHub issue, pull request description, or comment before posting
  • Writing release notes and changelog entries with correct headings and lists
  • Composing documentation or blog posts for a Markdown-based CMS or static site
  • Learning or testing Markdown syntax with instant visual feedback

Frequently asked questions

What is Markdown?

Markdown is a lightweight, plain-text formatting syntax that turns simple symbols into rich text -- for example, # for headings, ** for bold, and - for list items. It is the standard for README files, GitHub issues, and most documentation tools because it stays readable as plain text while rendering cleanly when formatted.

Is my data private?

Yes. The editor runs 100% client-side in your browser. Your Markdown is rendered locally and is never uploaded to a server, stored, or tracked -- so it is safe to preview private notes, internal docs, or unreleased content.

Is it free to use?

Yes, the Markdown Preview tool is completely free with no sign-up required. You can write and preview as much Markdown as you like.

How does the live preview work?

As you type in the editor, the tool parses your Markdown and re-renders the formatted preview in real time. There is no render button to press -- the preview reflects your latest edits instantly so you can iterate quickly.

What Markdown syntax does it support?

It supports GitHub-Flavored Markdown: headings, bold and italic text, ordered, unordered, and task lists, links, images, tables, strikethrough, blockquotes, inline code, and fenced code blocks. The rendered HTML is sanitized, so scripts and unsafe attributes never make it into the preview or the copied output.
