Frequently Asked Questions
Basics
What is Markdown?
Markdown is a lightweight markup language that lets you write formatted text using a plain text syntax. It was created by John Gruber in 2004 and is widely used for documentation, readme files, forums, and static site generators. This editor converts your Markdown into HTML in real-time.
How do I use this editor?
- Type or paste Markdown text into the editor panel.
- Switch between Editor, Preview, and Split view using the tab pills at the top.
- Use the formatting toolbar to quickly insert Markdown syntax.
- Click "Copy HTML" to copy the rendered HTML output to your clipboard.
What Markdown syntax is supported?
This editor supports: headings (H1 to H6), bold, italic, strikethrough, inline code and code blocks with syntax highlighting, links, images, ordered and unordered lists, blockquotes, horizontal rules, and tables. It uses a modified GitHub-Flavored Markdown syntax.
Usage Tips
What is the difference between Editor, Preview, and Split modes?
Editor mode shows the full-width textarea for writing Markdown without distractions. Preview mode hides the editor and shows only the rendered HTML output. Split mode displays both side by side so you can edit and see the result simultaneously — ideal for live editing.
How do I format text using the toolbar?
Select the text in the editor you want to format, then click the corresponding toolbar button. For example, select a word and click Bold to wrap it with **asterisks**. Click Link to wrap selected text in a Markdown link and you will be prompted for the URL. If no text is selected, the toolbar inserts placeholder text.
Is there a character limit?
No, there is no artificial character limit. Since all processing occurs in your browser, the practical limit depends on your device's memory and performance. For very large documents, consider saving your work periodically.
