Documents Conversion to PDF via Java Library

The open source Docs-to-PDF-Converter allows software developers to convert several document types into PDFs inside Java applications. The library supports Micro Word (DOC, DOCX), Excel (XLS, XLSX), PowerPoint (PPT, PPTX), RTF, OpenDocument Formats and many more. This broad format compatibility ensures seamless document conversion for diverse use cases. Here is a simple example that demonstrates, how software developers can convert a Word document (.docx) to PDF using Java commands.

import java.io.File;
import java.nio.file.Path;
import java.nio.file.Paths;
import yeokm1.docs2pdf.Converter;

public class DocumentConverter {
    public static void main(String[] args) {
        try {
            Path inputFile = Paths.get("input.docx");
            Path outputFile = Paths.get("output.pdf");
            
            Converter.convert(inputFile.toFile(), outputFile.toFile());
            System.out.println("Conversion successful! PDF saved at: " + outputFile);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Advanced Customization While Converting Docs to PDF

The open source Docs-to-PDF-Converter library allows software developers to customize the PDF output while converting documents to PDF. For example developers can control page size (A4, Letter, etc.), margins, orientation (portrait or landscape), and headers/footers. Moreover, they can apply CSS styles to HTML content for precise visual control, control font families, colors, sizes, and much more. The following code snippets shows how to apply various settings to the PDF generated by the library.

converter.setPageSize("A4"); // Set page size to A4
converter.setMargins(20, 20, 20, 20); // Set margins (top, bottom, left, right) in millimeters
converter.setFont("Arial"); // Set font to Arial

Handling Multiple File Formats

The Docs-to-PDF-Converter library empowers Java developers to create dynamic and sophisticated PDF documents with ease. It automatically detects the input file format and processes it accordingly. Whether it’s a Word, Excel, PowerPoint, or RTF file, the library seamlessly converts it to PDF without additional configurations. Here’s an example that shows how software developers can convert a Markdown file to PDF inside Java applications.

String inputFilePath = "path/to/your/document.md";
String outputFilePath = "path/to/output/document.pdf";

try {
    converter.convertToPdf(inputFilePath, outputFilePath);
    System.out.println("Markdown to PDF conversion successful!");
} catch (Exception e) {
    System.err.println("Conversion failed: " + e.getMessage());
}
