Converting PDF documents to HTML format for web publishing

PDF preserves layout, but it isn’t always the best format for web publishing. Convert PDF to HTML when you need to:

  • Publish document content on websites or intranets
  • Make content indexable by search engines
  • Reuse document content in web applications
  • Keep core layout and structure in browser-based output

Use the Java SDK for conversion

Use the Java SDK to add PDF-to-HTML conversion to your application workflow.

Preparing the project

Define a package and create a class for the conversion flow:

package io.nutrient.Sample;

Import Nutrient Java SDK classes. Prefer explicit imports for the classes you use:

import io.nutrient.sdk.Document;
import io.nutrient.sdk.exceptions.NutrientException;


public class PDFToHTML {

Create a main method and declare NutrientException:

    public static void main(String[] args) throws NutrientException {

Then add the SDK-specific conversion logic.

Proceeding with the conversion

This guide uses the Document class. Initialize it with a try-with-resources statement(opens in a new tab) to close resources correctly.

Open a source PDF by file path or stream. This example uses a file path:

        try (Document document = Document.open("input.pdf")) {

After loading the file, call SDK methods on the document instance. For the full API surface, refer to the API reference.

Configuring HTML output

Export the document as HTML:

            document.exportAsHtml("output.html");
        }
    }
}

The output keeps the document’s structure, including text, images, and formatting alignment.

Error handling

The SDK throws NutrientException when an operation fails. Handle this exception in your app for custom logging, retries, or fallback logic.

Conclusion

You now have a complete PDF-to-HTML conversion flow in Java. Download the sample package to run this example as-is.
