FAQ

    
This FAQ applies to product manuals, official website pages, course quizzes, and live Q&A.


    
1. What is Markdown Viewer?

    

      Markdown Viewer is a free online tool that renders Markdown into formatted HTML in real time.
      Write or paste Markdown on the left and see the formatted result on the right, then export it as
      PNG or PDF or copy the rendered HTML into a blog.
    


    
2. Which Markdown features are supported?

    
Markdown Viewer supports GitHub-Flavored Markdown (GFM), including:

    

    
3. How do I export to PNG or PDF?

    

      Choose PNG or PDF from the Export menu, then click Download.
      The export preserves your current font, font size, line height, margins and page size, so what you see
      in the preview is what you get in the file. PDF export is one click and produces a multi-page document.
    


    
4. Can I customize the rendering style?

    

      Yes. Click ⚙ Settings to change the font family, font size, line height, page margin and
      page size (A4 or Letter). Settings are saved in your browser and included in the share URL.
    


    
5. How do I copy the result into Medium or Substack?

    

      Click Copy. The rendered HTML is placed on your clipboard as rich text, so when you paste
      it into Medium, Substack, Gmail or Notion, the formatting (headings, lists, links, tables, images, math)
      is preserved. Medium and Substack re-style pasted content to match their theme.
    


    
6. Does it support LaTeX math?

    

      Yes. Use $...$ for inline math and $$...$$ for display math, rendered with KaTeX.
      Math inside fenced code blocks or inline code is shown literally and not rendered.
    


    
7. How do I share my Markdown?

    

      Click Share to copy a URL that encodes your Markdown (base64) plus your rendering settings.
      Anyone who opens the link sees the same document and style.
    


    
8. Is my content uploaded anywhere?

    

      No. Markdown is rendered entirely in your browser. The share URL encodes the content in the address
      itself, so nothing is sent to a server.
