The Online Markdown Editor is a free browser-based tool with live preview that lets you write, edit, and preview Markdown content in real time. The split-pane interface shows your raw Markdown on the left and the rendered HTML output on the right, updating instantly as you type. Whether you are writing README files, blog posts, documentation, or taking notes, this editor provides a distraction-free writing experience with the full power of Markdown formatting.The editor supports the complete CommonMark specification plus popular extensions including GitHub Flavored Markdown (GFM) features: task lists (checkboxes), tables, strikethrough, autolinks, and fenced code blocks with syntax highlighting. The toolbar provides quick-access buttons for common formatting — headings, bold, italic, links, images, code blocks, lists, and tables — so you don't need to memorize the syntax. You can export your content as HTML or copy the rendered output directly.Developers use this for writing README.md files, pull request descriptions, and documentation. Technical writers draft documentation in Markdown before publishing to static site generators (Jekyll, Hugo, Gatsby). Bloggers compose content in Markdown for CMS platforms that support it. Students take structured notes with headings, code blocks, and formula notation. Project managers write specifications and meeting notes in a portable, version-control-friendly format. All editing happens locally in your browser with no account required.Online Markdown Editor is part of the facilita.tools developer toolkit. Available in Portuguese, English, and Spanish, optimized for desktop and mobile.
Frequently Asked Questions
What is Markdown?
Markdown is a lightweight markup language for creating formatted text using a plain-text editor. Created by John Gruber in 2004, it is widely used for README files, documentation, forums, and messaging. It converts to HTML and is supported by GitHub, Stack Overflow, Reddit, and many other platforms.
How do I create a table in Markdown?
Use pipes (|) and hyphens (-) to create tables. Example: | Header 1 | Header 2 | followed by | --- | --- | for the separator, then | Cell 1 | Cell 2 | for data rows. Alignment is controlled with colons: :--- (left), :---: (center), ---: (right).
What is GitHub Flavored Markdown (GFM)?
GFM is an extended version of Markdown used by GitHub. It adds features like task lists (- [x]), tables, strikethrough (~~text~~), fenced code blocks with syntax highlighting, autolinked URLs, and emoji shortcodes (:emoji:).
