Markdown is a lightweight markup language that converts plain text into HTML. You write formatting using simple symbols: **bold**, *italic*, # for headings, - for lists, and backticks for code. A Markdown parser reads these symbols and renders formatted HTML. It is widely used for README files, documentation, blog posts, and content management systems because of its readability as plain text.
GitHub Flavored Markdown (GFM) is GitHub's extension of standard Markdown. It adds support for tables, fenced code blocks with syntax highlighting, task lists (checkboxes), strikethrough text, and autolinked URLs. This tool supports GFM, so you can preview exactly how your README files and GitHub documentation will render before pushing them to a repository.
Create a Markdown table using pipe characters and hyphens. The first row is the header; the second row uses dashes to separate header from body; subsequent rows are data. Example: | Name | Age | on the first line, | --- | --- | on the second. Colons in the separator control alignment: :--- left, :---: center, ---: right. GFM tables render beautifully in this preview.
Yes. Click the HTML tab to see the rendered HTML output of your Markdown. Copy the HTML and paste it directly into a website, email template, or CMS. The exported HTML preserves all formatting including headings, code blocks, tables, and task lists. All processing is 100% client-side — your content never leaves your browser and is never sent to any server.
Add syntax-highlighted code blocks using triple backticks followed by the language name. Start with ``` javascript (three backticks then the language), write your code, then close with three more backticks. This tells the renderer to apply syntax highlighting for that language. Supported languages include JavaScript, Python, Bash, SQL, CSS, HTML, TypeScript, and many more.
