Summary — What Free Markdown Live Preview Does
What This Free Tool Is
Free Markdown Live Preview is a distraction-free editor that renders your Markdown as you type. Headings, lists, tables, code blocks, blockquotes, and GFM task lists all appear instantly in the right pane. Perfect for drafting blog posts, README files, or any Markdown document where you want to see what you're writing as it will appear to readers.
Privacy: This tool runs entirely in your browser. Your text is never uploaded, logged, or cached. Close the tab and it's gone. Verify in DevTools → Network: zero requests fire.
Why It's Free (And How We Keep It Free)
The tool is built from a tiny Markdown parser and some CSS. The Cloudflare bill is negligible. No VC pressure, no signup funnel — just a fast, pretty editor.

Markdown Live Preview Features
Here's what this free tool does in detail — every feature is built to solve real problems, runs entirely in your browser, and is free forever.
Real-Time Rendering on Every Keystroke
Every character you type updates the rendered preview instantly — no debounce, no lag, no 'refresh preview' button. Headings grow as you type, lists indent as you add dashes, code blocks appear as soon as you close the fence. The preview is as fast as the keyboard, no matter how long your document gets.
When you're done drafting and need the final HTML for a blog or CMS, switch to the Free Markdown to HTML Converter with the one-click ⇄ swap button at the top.
Split-Pane Editor with Independent Scrolling
Markdown source on the left, fully-rendered preview on the right — each pane scrolls independently so you can edit a paragraph mid-document while watching the end-of-doc conclusion render. On viewports under 768px the layout collapses to a single column so it stays usable on mobile.
Need a quick word count while you draft? Every keystroke also updates the word count and reading time in the toolbar — same logic as the Free Markdown Word Counter.
HTML Source Toggle
Click Show HTML source to replace the rendered preview with the raw rendered HTML output. Useful for inspecting or copying the HTML, debugging why something isn't rendering, or grabbing the HTML for a platform that doesn't accept Markdown. Toggle back with Show rendered to return to the visual view.
For a one-shot Markdown-to-HTML conversion without the live-editing overhead, use the Free Markdown to HTML Converter instead.
GitHub-Flavored Markdown + CommonMark
GFM is the default — it's the flavor your GitHub README, GitLab wiki, Obsidian vault, Notion page, and Dev.to post use. GFM adds tables, task lists (- [x]), strikethrough (~~text~~), autolinks, and fenced code blocks with language hints on top of the CommonMark baseline. Toggle to CommonMark for strict spec-compliant rendering if your target renderer demands it.
When you need to parse your Markdown into a structured AST instead of rendering to HTML, the Free Markdown to JSON tool produces a token tree you can use in code.
Runs 100% in Your Browser
The preview rendering, the keystroke handling, everything — all happens inside your browser tab via JavaScript. Your draft is never uploaded, auto-saved to cloud, or synced anywhere. Close the tab and every trace is gone. This makes Live Preview usable for sensitive drafts — product specs, legal text, unpublished articles — without worrying about where the text goes.
Same privacy model across the site: Free Markdown Formatter, Free HTML to Markdown, and every other client-side tool runs entirely in your browser.
Word Count + Reading Time in the Toolbar
See word count and estimated reading time update as you write. Reading time uses 225 wpm — the standard average silent reading rate. Useful for hitting blog-post targets (typically 1500–2500 words for SEO), meeting assignment requirements, or estimating reader dwell time.
For a dedicated counter with 8 metrics (words, chars, paragraphs, sentences, lines, reading/speaking time), use the Free Markdown Word Counter.
