💻 Code Examples

Convert DOCX to PDF

This example loads a Word document and converts it to PDF. The Converter class accepts a file path and auto-detects the source format. You then pass a format-specific options object — here PdfConvertOptions — to the Convert() method along with the output path. Replace PdfConvertOptions with WordProcessingConvertOptions, SpreadsheetConvertOptions, or PresentationConvertOptions to target other formats.

using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;

// Convert Word document to PDF
using (var converter = new Converter("document.docx"))
{
    var options = new PdfConvertOptions();
    converter.Convert("document.pdf", options);
}

See the Conversion documentation for the full list of supported format pairs and available options.

Merge Multiple PDFs into One

This example merges two PDF files into one. Create a Merger with the first file, call Join() for each additional file, then call Save() to write the result. You can chain multiple Join() calls to combine more than two files. The same pattern works for Word, Excel, PowerPoint, and other supported formats.

using GroupDocs.Merger;

// Merge two PDF files into a single document
using (var merger = new Merger("document1.pdf"))
{
    merger.Join("document2.pdf");
    merger.Save("merged.pdf");
}

See the Merger documentation for splitting, page reordering, and other operations.

Extract Text from a Document

This example extracts all text from a PDF file. The Parser class opens the document and GetText() returns a standard TextReader with the full content. If the format doesn't support text extraction, GetText() returns null. Beyond plain text, you can use GetTables(), GetImages(), GetMetadata(), and GetBarcodes() to extract structured content.

using GroupDocs.Parser;

// Extract all text from a PDF document
using (var parser = new Parser("document.pdf"))
{
    using (TextReader reader = parser.GetText())
    {
        Console.WriteLine(reader == null
            ? "Text extraction isn't supported"
            : reader.ReadToEnd());
    }
}

See the Parser documentation for page-level extraction, table parsing, and other options.
