HTML to Markdown Converter

Convert HTML code to Markdown text.

Overview

The HTML to Markdown Converter is an online tool built with Blazor (C#) that converts HTML markup into clean, readable Markdown. It is ideal for developers, bloggers, and technical writers who want to migrate existing HTML content into Markdown for use in documentation, static site generators, or version-controlled content workflows.

This tool is powered by the ReverseMarkdown NuGet package, a robust .NET library that translates HTML elements into their Markdown equivalents while preserving structure and readability.

What the Tool Does

The HTML to Markdown Converter performs the following tasks:

• Accepts .html, .txt, or .md files containing HTML markup
• Allows users to paste or write raw HTML directly into a text area
• Converts HTML elements into Markdown syntax using ReverseMarkdown
• Outputs the resulting Markdown text into a dedicated output area

The generated Markdown can be used directly in Markdown editors, Git repositories, static site generators, or CMS platforms that support Markdown.

How to Use the Tool

1. Provide HTML Input

   • Upload a file containing HTML
     or
   • Paste or type HTML into the input text area

2. Generate Markdown

   • Click the Generate button

3. Copy the Result

   • The converted Markdown will appear in the output text area
   • Copy and reuse the Markdown anywhere you need it

Key Terms Explained

HTML (HyperText Markup Language)

HTML is the standard markup language for structuring content on the web. While powerful, HTML can be verbose and less readable in raw form.

Example:

<h1>Hello World</h1>
<p>This is <strong>bold</strong> text.</p>

Markdown

Markdown is a lightweight markup language that uses simple syntax for formatting text. It is easier to read and write compared to raw HTML.

Equivalent Markdown:

# Hello World
This is **bold** text.

ReverseMarkdown

ReverseMarkdown is a .NET library that converts HTML into Markdown. It supports:

• Headings, paragraphs, and lists
• Links and images
• Inline formatting (bold, italic, code)
• Customizable conversion rules

Example: Implementing HTML to Markdown in C#

Below is a simple example showing how you can convert HTML to Markdown in your own C# application using ReverseMarkdown.

1. Install the ReverseMarkdown NuGet Package

dotnet add package ReverseMarkdown

2. Create a Conversion Function

using ReverseMarkdown;

public static class HtmlToMarkdownConverter
{
    public static string ConvertToMarkdown(string html)
    {
        if (string.IsNullOrWhiteSpace(html))
            return string.Empty;

        var converter = new Converter(new Config
        {
            GithubFlavored = true,
            RemoveComments = true,
            SmartHrefHandling = true
        });

        return converter.Convert(html);
    }
}

3. Usage Example

string htmlContent = @"
<h1>HTML to Markdown</h1>
<p>This is <strong>bold</strong> and <em>italic</em> text.</p>
<ul>
    <li>Item One</li>
    <li>Item Two</li>
</ul>
";

string markdown = HtmlToMarkdownConverter.ConvertToMarkdown(htmlContent);

// markdown now contains the converted Markdown text
