Converting PDF documents to HTML format for web publishing

Converting PDF documents to HTML format — whether making document content searchable, embedding it in webpages, or improving accessibility for screen readers — opens up numerous possibilities for content distribution and accessibility.

How Nutrient helps you achieve this

Nutrient .NET SDK handles PDF-to-HTML conversion. With the SDK, you don’t need to worry about:

• Parsing PDF document structures
• Managing HTML layout generation
• Handling font and style conversion
• Complex rendering logic

Instead, Nutrient provides an API that handles all the complexity behind the scenes, letting you focus on your business logic.

Complete implementation

Below is a complete working example that demonstrates PDF-to-HTML conversion. This line sets up the C# application. The using directive brings in the Nutrient SDK namespace:

using Nutrient;

This line opens the PDF file. The using declaration(opens in a new tab) ensures the document is automatically closed when it goes out of scope, preventing resource leaks:

try
{
    using Document document = Document.Open("input.pdf");

This block exports the PDF content to HTML and saves it as output.html. The try-catch block handles potential errors using NutrientException:

    document.ExportAsHtml("output.html");
    Console.WriteLine("Successfully converted to output.html");
}
catch (NutrientException e)
{
    Console.Error.WriteLine($"Error: {e.Message}");
    Environment.Exit(1);
}

Conclusion

The conversion logic consists of two steps:

1. Open the document.
2. Export as HTML.

Nutrient handles PDF parsing and HTML generation so you don’t need to understand PDF internals or manage layout conversion manually.
