ACERCA DE ESTA HERRAMIENTA

Write or paste Markdown into the left pane and watch the rendered HTML update instantly on the right as you type. The previewer follows common GitHub-flavored Markdown conventions, so headers, bold and italic text, ordered and unordered lists, blockquotes, fenced code blocks, tables, and inline links all render the way they would on GitHub or most static site generators. Everything runs in your browser, so nothing you write is uploaded anywhere. It's a fast way to check formatting before committing a README, drafting a blog post in Markdown, or writing documentation without installing an editor or setting up a local build.

CÓMO USARLO

1. Paste or type your Markdown into the input pane on the left.
2. Watch the rendered HTML update automatically in the preview pane as you type.
3. Use standard syntax - # for headers, ** for bold, - for lists, ``` for code blocks.
4. Check that tables and nested lists render the way you intended before publishing.
5. Copy the finished Markdown back out once the preview looks right.

CASOS DE USO COMUNES

• A developer drafting a README.md for a new GitHub repo before committing it.
• A technical writer previewing a docs page before it goes into a static site generator like Hugo or Jekyll.
• A blogger writing a post for a platform like Dev.to or Ghost and checking formatting first.
• Someone writing release notes and confirming bullet lists and code snippets render cleanly.
• A beginner learning Markdown syntax by watching each element render in real time.

CONSEJOS Y ERRORES COMUNES

• Fenced code blocks need a blank line before and after them or they may merge with surrounding text.
• GitHub-flavored tables require a header row plus a separator row (|---|---|) or they won't render as a table.
• Nested lists need consistent indentation - mixing tabs and spaces can break the nesting.
• Raw HTML dropped into Markdown usually passes through unchanged, since most Markdown parsers don't strip embedded HTML.

MÁS PREGUNTAS

Does this support GitHub-flavored Markdown extras like tables and strikethrough?

Yes, it supports GFM extensions such as tables, strikethrough (~~text~~), and fenced code blocks with language hints, in addition to standard CommonMark syntax.

Will the preview match exactly how GitHub or my static site generator renders it?

Close, but not guaranteed identical - renderers like GitHub, Jekyll's Kramdown, and Hugo's Goldmark differ slightly on edge cases like footnotes, so spot-check anything unusual on the actual target platform.

Can I preview Markdown with embedded images?

Image syntax like  renders if the URL is publicly reachable, but local file paths won't resolve since the tool runs in your browser with no file system access.

What happens with malformed Markdown, like an unclosed code fence?

The parser makes a best effort and typically treats everything after it as part of the open block, which is actually a handy way to spot the mistake since the preview will look obviously wrong.
