RELATED TOOLS

FREQUENTLY ASKED QUESTIONS

Is my content saved anywhere?

No. Everything stays entirely in your browser. Nothing is sent to any server. Your Markdown is only stored in the page's memory while it's open โ€” refreshing will clear it unless your browser restores the session.

What Markdown syntax is supported?

This editor supports GitHub Flavored Markdown (GFM) โ€” headings, bold, italic, strikethrough, blockquotes, ordered and unordered lists, task lists, fenced code blocks with language hints, tables, inline code, links, and images.

Can I export my document?

Yes. You can download the raw Markdown as a .md file, or copy the rendered HTML output to your clipboard for pasting into a CMS, email, or website.

Does it support syntax highlighting in code blocks?

The editor renders fenced code blocks with proper formatting and a monospace font. Full syntax colorization is not included in this lightweight tool โ€” for that, use a dedicated code highlighter like highlight.js in your final project.

Can I resize the editor and preview panes?

Yes. Drag the divider between the two panes to adjust their widths. You can also switch between Edit-only, Split, and Preview-only modes using the buttons in the toolbar.

Does it work on mobile?

Yes. On smaller screens the layout switches to a stacked view with tabs to toggle between the editor and preview. The toolbar scrolls horizontally for easy access to all formatting buttons.

What Is a Markdown Editor?

A Markdown editor is a text editor that renders Markdown syntax as formatted HTML in real time. Instead of writing raw HTML tags, you use lightweight symbols like # for headings, ** for bold text, and - for list items. The editor translates these into clean, readable HTML that displays instantly in the preview pane.

Markdown was created by John Gruber in 2004 with the goal of making web writing as readable and writable as possible. Today it is the standard format for GitHub README files, technical documentation, static site generators like Jekyll and Hugo, and countless note-taking apps like Obsidian and Notion.

Why Use an Online Markdown Editor?

An online Markdown editor is useful when you need to write or proof Markdown without installing any software. You get instant feedback on your formatting as you type, which is especially helpful when you are learning Markdown syntax or when you want to check exactly how your tables, task lists, or nested lists will render.

This tool is entirely browser-based. There is no sign-up, no account, and no data ever leaves your device. It is ideal for quickly drafting a README, writing documentation, or converting a block of Markdown into HTML that you can paste into a CMS or email template.

Supported Markdown Syntax

This editor supports the full GitHub Flavored Markdown (GFM) specification, which is a widely-used superset of the original CommonMark standard. Here is what is supported:

How the Live Preview Works

As you type in the editor, the Markdown is parsed and converted to HTML using a client-side JavaScript library. The preview pane updates within milliseconds. There is no network request โ€” the parsing happens entirely in your browser, which means it works offline once the page is loaded.

The split-pane layout lets you write on the left and see the result on the right simultaneously. If you prefer a distraction-free writing experience, you can switch to Edit-only mode. When you want to review the final output, switch to Preview-only mode for a clean, full-width render of your document.

Exporting Your Markdown

Once you have finished writing, you have two export options. The Download .md button saves your raw Markdown source as a file with the .md extension, which you can commit to a Git repository, open in VS Code, or upload to a documentation platform. The Copy HTML button copies the fully rendered HTML to your clipboard, ready to paste into a blog, newsletter, or CMS that accepts HTML input.

Markdown in the Modern Web

Markdown has become the de facto standard for developer documentation because it is easy to read as plain text and easy to convert to HTML. Every major code hosting platform (GitHub, GitLab, Bitbucket) renders Markdown natively. Static site generators like Jekyll, Hugo, Eleventy, and Astro use Markdown as their primary content format. Note-taking tools like Obsidian, Bear, and Notion all support Markdown input.

Understanding Markdown is an essential skill for any developer or technical writer. This editor gives you a fast, no-friction environment to practice, draft, and proof your Markdown before committing it to a repository or publishing it to the web.
