What is a Markdown Editor?
A Markdown editor is a specialized writing tool that provides an optimized environment for creating content using Markdown syntax. Unlike a plain text editor, a Markdown editor typically offers split-pane or WYSIWYG interfaces that show both the raw Markdown and the formatted output simultaneously.
FormatList's Markdown Editor provides a clean, distraction-free interface with live preview, syntax highlighting, and full GFM support — all running locally in your browser.

How to Use a Markdown Editor
Open the Editor
Navigate to the editor page. The split-pane interface shows your writing space on the left and the live preview on the right.
Start Writing
Type Markdown syntax directly into the editor. Use # for headings, * for lists, ** for bold, and so on. The preview updates instantly.
Format as You Go
Add formatting elements like links, images, code blocks, and tables using standard Markdown syntax. The preview confirms your formatting.

Markdown Writing Tips
Get the most out of your Markdown editor with these tips:
- Use headings consistently — Start with a single # for the title, then ## for sections, ### for subsections. This creates a clear document hierarchy.
- Separate sections with blank lines — Always put a blank line between headings and content to ensure proper rendering.
- Preview tables carefully — Table formatting can be tricky. Use the live preview to verify alignment and column layout.
- Use fenced code blocks — Specify the language after the opening triple backticks for syntax highlighting.
- Test your links — Use the preview to verify that links render correctly before publishing.
FAQ
What's the difference between Markdown and WYSIWYG editors?
WYSIWYG editors hide the underlying formatting code, while Markdown editors let you see and control the raw syntax. Markdown gives you more control and produces cleaner output.
Can I upload files to the Markdown editor?
Yes. You can upload .md files to load content into the editor. You can also copy and paste Markdown content directly.
Does the editor support image embedding?
Yes. Use the standard Markdown image syntax  and images will render in the preview pane.
