What does this tool do?
The MagmaNex Markdown Editor is a split-pane editor that renders your formatting in real time as you type. It supports GitHub Flavored Markdown including headings, bold and italic text, links, code blocks, tables, and blockquotes, while tracking word, character, and line counts live. It is ideal for bloggers, developers, and anyone drafting a README.
How to use it
- Paste your text into the input area.
- Adjust the options to fit your needs.
- Copy the processed text.
Three view modes and export
The editor offers Split, Preview, and Source views. In Split mode you write Markdown on the left and watch the rendered result on the right in real time. When you are done, download your document as a .md file with one click, or as a complete .html file with styling embedded so it opens directly in any browser. You can also reveal the generated HTML source, copy it, and paste it into your own site.
Safe and private rendering
All conversion happens in your browser; your text is never sent to a server. As the preview is built, the HTML output is cleaned with DOMPurify, so script tags, javascript: links, and event attributes like onerror are stripped out. This means you can safely preview Markdown copied from another source without any XSS risk.
Frequently asked questions
Does it support GitHub Flavored Markdown tables?
Yes. Because GFM is enabled, pipe-delimited tables, task lists, strikethrough text, and line breaks are parsed correctly and appear as real tables in the preview.
Why does the downloaded HTML file look ready to use?
The HTML export embeds base styling for headings, code blocks, tables, and blockquotes. You can open the file directly in a browser, or edit the style block to customize its appearance.
Can I see how long my text is?
Yes. A live counter below the toolbar shows word, character, and line totals that update instantly as you type.
