Converting PDF to HTML

Markdown version of this page, suitable for AI agents and automation

PDF files preserve fixed layout, but web applications often need HTML content. Converting PDF to HTML helps you publish document content in browser-based systems.

Use this workflow when you need to:

  • Publish PDF content on websites or intranets
  • Index document content for web search
  • Integrate document output into HTML-based pipelines

Project setup

Install:

  • The core Nutrient Native SDK package
  • GdPicture.Resources for HTML conversion support

Prepare the project

Register the SDK license before running conversion operations. For setup details, refer to the getting started with .NET SDK guide.

using GdPicture14;


LicenseManager licence = new LicenseManager();
licence.RegisterKEY("");

Create the document converter

Instantiate GdPictureDocumentConverter:

using GdPictureDocumentConverter converter = new GdPictureDocumentConverter();

Load the PDF document

Load the source PDF file:

converter.LoadFromFile(@"input.pdf");

For available converter methods, refer to the API reference guide.

Configure HTML output

Save the document as HTML with page-layout output:

converter.SaveAsHTML(@"output.html", HtmlLayoutType.PageLayout);

HtmlLayoutType.PageLayout keeps output close to the original page structure.

Handle errors

LoadFromFile and SaveAsHTML return GdPictureStatus values. Use those values in your error handling flow. For status-handling patterns, refer to the handling errors with .NET SDK guide.

Conclusion

This guide converts a PDF document to HTML for web-based publishing and integration.
