How the Markdown Preview Works
- 1Type or paste your Markdown source into the left panel. A sample document is pre-loaded so you can see the preview immediately.
- 2The rendered preview on the right updates live as you type — headings, lists, code blocks, and formatting are all rendered instantly.
- 3Check word count and character count in the stats bar below the editor — useful for blog posts and documentation with length targets.
- 4When the preview looks right, copy your Markdown source and paste it into your CMS, static site generator, or documentation tool.
Why Live Preview Matters
Markdown is easy to misread when written as plain text. A heading created with #looks like commented-out text at a glance; a blockquote starting with >can be confused for an angle bracket. A live preview eliminates that ambiguity — what you see on the right is what your readers will see. This is especially valuable when writing documentation, README files, or blog posts where formatting correctness matters.
Tips for Writing Markdown
Use blank lines between blocks
A blank line separates paragraphs, headings, lists, and code blocks. Without blank lines, consecutive content merges into a single paragraph in the rendered output.
Label your code fences
Opening a code block with a language name (```python) enables syntax highlighting in most renderers and CMSs. The preview shows the label — the highlighter is applied by the publishing platform.
Preview before publishing
Check your Markdown in the preview before copying it to your CMS. Catching a missing asterisk or a broken link here is faster than fixing it after publishing.
Check heading hierarchy
Screen readers and search engines rely on correct heading order (h1 → h2 → h3). Use the preview to confirm you are not skipping levels or using multiple h1s in the same document.
Copy the HTML when needed
If you need the raw HTML source rather than the visual preview, use the Markdown to HTML Converter — it outputs the HTML string with a one-click copy button.
Frequently Asked Questions
Does this Markdown preview tool require any libraries or plugins?
No. The Markdown parser is written in plain TypeScript and runs entirely in your browser — no external libraries, no CDN requests, and no backend. Everything executes client-side the moment you type.
Which Markdown syntax is supported in the preview?
The previewer supports ATX headings (# through ######), bold, italic, bold+italic, strikethrough, inline code, fenced code blocks with language hints, unordered lists, ordered lists, blockquotes, links, images, and horizontal rules. This covers CommonMark core and the everyday GitHub Flavored Markdown (GFM) subset.
Is my Markdown text sent to a server?
No. The preview is rendered entirely in your browser using JavaScript. Nothing you type is transmitted over the network. Your content stays on your device at all times.
How is this different from the Markdown to HTML Converter?
The Markdown to HTML Converter outputs the raw HTML source code — useful when you need to copy the markup. The Markdown Preview tool renders the HTML visually, styled like a document — useful when you want to check how the content will look to a reader. Both tools use the same underlying parser.
Can I copy the rendered HTML from the preview?
The preview panel renders the HTML visually rather than as source code. To get the raw HTML string, use the Markdown to HTML Converter — it outputs copyable HTML source with a one-click Copy button.
Does the preview match GitHub Markdown exactly?
For common elements (headings, lists, code, links, images, blockquotes) the rendering is equivalent. Edge cases like task lists (- [ ]), footnotes, and HTML tables have no direct equivalent in this lightweight implementation. For full GitHub Flavored Markdown, test your content in a GitHub repository README.
