About Markdown Preview
Markdown is a lightweight markup language created by John Gruber. It's the standard for README files, documentation, blog posts, and technical writing across GitHub, GitLab, Stack Overflow, and countless platforms.
This tool renders your Markdown to HTML in real-time using GitHub Flavored Markdown (GFM), supporting tables, task lists, strikethrough, fenced code blocks, and autolinks.
Everything runs 100% in your browser. Your text never leaves your device — no server, no tracking, no account required.
Frequently Asked Questions
How do I preview Markdown online?▼
Simply paste or type your Markdown text into the editor on the left. The rendered preview appears instantly on the right. You can switch between Split view, Preview-only, and HTML output modes using the toolbar buttons.
Does this support GitHub Flavored Markdown (GFM)?▼
Yes! This tool fully supports GFM including tables, task lists (checkboxes), strikethrough (~~text~~), fenced code blocks with language hints, autolinks, and line breaks. It matches how GitHub renders README.md files.
Can I export Markdown to HTML?▼
Yes. Switch to HTML view to see and copy the raw HTML output, or click 'Export HTML' to download a complete, styled HTML file ready to use in any website or email.
Is my text stored or sent to a server?▼
No. This Markdown preview tool runs 100% in your browser using the 'marked' JavaScript library. Your text never leaves your device — there is no server processing, no uploads, and no tracking.
What Markdown syntax is supported?▼
All standard Markdown plus GFM extensions: headings (#), bold (**text**), italic (*text*), links, images, lists (ordered and unordered), blockquotes, code blocks (inline and fenced), tables, task lists, horizontal rules, and strikethrough.
Can I use this as a README editor for GitHub?▼
Absolutely. This tool uses the same GFM rendering that GitHub uses. Write your README here, preview it, then copy the Markdown into your repository's README.md file. The output will look identical on GitHub.
