Markdown Guide: Write, Preview and Convert

Core syntax in five minutes

  • Headings: # H1 through ###### H6
  • Emphasis: bold, italic, ~~strikethrough~~
  • Lists: - unordered and 1. ordered
  • Links & images: text, ![alt text](image URL)
  • Code: inline ` code `, and fenced blocks with triple backticks
  • Quotes: > quoted text
  • Horizontal rule: ---

Step 1: write left, preview right

Open HeronTool's Markdown Editor:

  1. Type Markdown on the left;
  2. See the rendered preview on the right in real time;
  3. Need web code? Copy the HTML output in one click.

You see the finished result as you type — no toggling back and forth.

Step 2: Markdown to HTML

Putting Markdown content into a webpage, email or CMS? Use the Markdown to HTML tool:

  1. Paste your Markdown;
  2. Click convert;
  3. Copy the generated HTML and paste it where it belongs.

Writing tips

  • Structure first: outline with headings, then fill in — long posts stay on track;
  • Use sparingly: too much emphasis or listing distracts rather than helps;
  • Localize images: download hotlinked images before publishing to avoid broken pictures;
  • Specify code languages: fenced blocks like ```js get syntax highlighting.

FAQ

Q: Can Markdown and rich text convert into each other?
Yes. Most editors convert pasted rich text into Markdown, and Markdown can be exported to Word/PDF via renderers or conversion services.

Q: Why isn't my table rendering?
Tables are a GFM (GitHub Flavored Markdown) extension; some pure Markdown parsers lack support. Confirm the platform/editor supports table syntax.

Q: Can I undo a mistake?
Markdown is plain text; with Git or a notes app's version history you can always roll back — a natural advantage.

In summary

Five minutes of syntax, real-time preview, one-click conversion — that's the whole everyday Markdown workflow. Write and watch it render on HeronTool, and you'll have the full loop working in one go.
