Markdown Editor

About the Markdown Editor

What is this tool?

This is a live Markdown editor: you write Markdown on the left and the formatted result appears on the right as you type. It speaks GitHub Flavored Markdown, so tables, task lists, strikethrough and fenced code blocks all work, and code is syntax-highlighted. A formatting toolbar sits above the editor for the moments you cannot remember whether it is one asterisk or two, and the two panes scroll together so you never lose your place in a long document.

Everything happens in your browser — the Markdown parser, the sanitizer and the highlighter all run on your machine, and nothing you type is uploaded. When you are done you can copy the Markdown, copy the rendered HTML, or download either one as a file. The preview is sanitized with DOMPurify, so even if you paste Markdown that contains raw HTML, nothing dangerous can run.

How to Use This Tool

1. Start typing. The preview updates instantly. Load the sample if you want to see every supported feature at once.
2. Use the toolbar or shortcuts. Select text and click a button, or press Ctrl/Cmd + B for bold, I for italic and K for a link. Tab indents instead of leaving the editor.
3. Watch the stats. Word, character and line counts and an estimated reading time update as you write.
4. Take it with you. Copy the Markdown or the HTML, or download a .md or .html file — and use the linked converter if you need a PDF.

Common Use Cases

What people reach for a live Markdown editor to do:

• READMEs and docs: write your project's README and see exactly how GitHub will render the tables and task lists before you commit.
• Blog posts and CMS content: draft in Markdown, then copy the clean HTML straight into your platform.
• Notes and outlines: a distraction-free place to think in headings and lists.
• Learning Markdown: the toolbar shows you the syntax it inserts, so you pick it up by watching.
• Related tools: export the result with the Markdown to PDF converter, format existing HTML with the HTML formatter, or preview raw HTML in the HTML viewer.

Frequently Asked Questions

What is Markdown?

Markdown is a lightweight way to format plain text using simple symbols — a hash for a heading, asterisks for bold, a dash for a list item. It was created by John Gruber in 2004 and is now the standard for READMEs, documentation, chat apps and static site content because it stays readable as plain text while still producing formatted output.

Does this editor support tables and task lists?

Yes. It renders GitHub Flavored Markdown, which adds tables, task list checkboxes, strikethrough and automatic links on top of standard Markdown. The toolbar has one-click buttons for tables and task lists, and the sample document demonstrates all of them.

Is my text private?

Completely. The editor, the preview, the sanitizer and the syntax highlighter all run in your browser on your own device. Nothing you type is sent to a server, so drafts, notes and internal documentation are safe to write here.

How do I get the HTML out?

Click Copy HTML to put the rendered HTML on your clipboard, ready to paste into a website, blog or email. Or click Download .html to save a complete standalone HTML file. The HTML is the sanitized output from the preview, so it is safe to reuse.

Are there keyboard shortcuts?

Yes. Ctrl or Cmd + B wraps the selection in bold, + I makes it italic, and + K turns it into a link. Pressing Tab inserts an indent instead of moving focus out of the editor, which is handy for nested lists and code.

Why is the code in my code blocks colored?

Fenced code blocks are syntax-highlighted so they are easier to read, using the same highlighter many documentation sites use. Add a language after the opening backticks — like three backticks followed by js — to hint the language, though it is usually detected automatically.

Can I turn my Markdown into a PDF?

Yes — the Markdown to PDF converter, linked above the About section, takes the same Markdown and produces a paginated PDF, either as a downloaded file or through your browser's print dialog for selectable text. Write here, export there.
