For details, visit the GroupDocs’ purchase page or request a temporary license.

Basic Initialization

Create a Converter instance pointing to your source document:

import com.groupdocs.conversion.Converter;

// Initialize the converter with your document path.
Converter converter = new Converter("YOUR_DOCUMENT_DIRECTORY/SAMPLE_DOCX");

How to set PDF page number for page‑range conversion

Step 1: Configure conversion options

Use PdfConvertOptions to define the start page and how many consecutive pages you want to include:

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

// Create an instance of PdfConvertOptions.
PdfConvertOptions options = new PdfConvertOptions();

// Set the starting page and total number of consecutive pages to convert.
options.setPageNumber(2);
options.setPagesCount(2);

Pro tip: Adjust setPageNumber to the exact page where your content begins. The setPagesCount value determines how many pages after that start point are included, enabling convert specific pages pdf workflows.

Step 2: Perform the conversion

Specify the output path and run the conversion:

// Define where the converted PDF will be saved.
String convertedFile = "YOUR_OUTPUT_DIRECTORY/ConvertNConsecutivePages.pdf";

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

Key Configuration Options Recap

  • PageNumber: Starting page for the PDF output.
  • PagesCount: Number of consecutive pages to include.

These settings let you convert specific pages pdf while keeping the rest of the document untouched.

Common Issues & Solutions

  • Invalid file paths: Double‑check that both input and output directories exist and are readable.
  • Unsupported source format: Ensure your document type is listed in the GroupDocs supported formats.
  • Page range exceeds document length: The conversion stops at the last available page without throwing an error.

Practical Use Cases

  1. Legal contracts: Export only the clauses relevant to a client.
  2. Educational handouts: Share a single chapter from a textbook.
  3. Business reports: Distribute a concise summary by extracting key pages.

Performance Tips

  • Use Java’s try‑with‑resources to automatically close streams.
  • Process large files in batches to avoid memory spikes.
  • Keep the GroupDocs library up‑to‑date for the latest performance improvements.
