Implementation Guide

Now, let’s delve into how you can implement document conversion using GroupDocs.Conversion in your Java application.

Conversion Setup and Execution

Overview

The core functionality here is to take a source document and convert it into a PDF file. This process involves setting up the Converter instance and specifying the output path for the converted file.

Step 1: Define Output Path

You must specify where the PDF should be saved after conversion. Replace 'YOUR_OUTPUT_DIRECTORY' with your desired directory.

String convertedFile = "YOUR_OUTPUT_DIRECTORY/converted.pdf";

This step is crucial as it determines where the output file will reside.

Step 2: Execute Conversion

Using the Converter instance, you can execute the conversion:

import com.groupdocs.conversion.options.convert.PdfConvertOptions;

// Initialize Converter with source document path
Converter converter = new Converter("source_document_path");

// Create PdfConvertOptions instance to specify conversion options
PdfConvertOptions options = new PdfConvertOptions();

// Convert and save the document as PDF
converter.convert(convertedFile, options);

Explanation:

  • PdfConvertOptions: Configures how the output PDF should be rendered. You can customize settings like page size, margins, etc.
  • converter.convert(): Executes the conversion based on the provided path and options.

Troubleshooting Tips

If you encounter issues during setup or conversion:

  • Ensure all dependencies are correctly specified in your pom.xml.
