jOfficeConvert is a Java library that can read Word documents and then convert to PDF, or render them into images or to a printer. jOfficeConvert can be integrated into your Java application or applet to allow you to provide conversion functionality to your users. jOfficeConvert provides the following functions:

  • Convert Word documents (doc and docx) to PDF
  • Convert Excel spreadsheets (xlsx) to PDF
  • Set permissions and passwords on the converted PDF documents
  • Convert pages to JPEG, TIFF or PNG images
  • Print Word documents automatically
  • No third party software or drivers necessary
  • Support for JDK 1.6 and above
  • Save to the file system or to Java output streams

Like all of our libraries, jOfficeConvert is built using Qoppa’s proprietary technology and so does not require any third party software or drivers.

Convert Word To PDF

The starting point is the com.qoppa.word.WordDocument class. This class is used to load Word documents and then provides methods to save as a PDF document, to convert to images and to print the document.

The class provides constructors to load Word documents from files, URLs, input streams or byte arrays. To convert a Word file from the file system to PDF, there are only a few lines of code needed to set the conversion options, load the Word document and then save it to PDF:

// Create an Object to store the conversion options
WordConvertOptions opts = new WordConvertOptions();
// Set option to embed fonts to true
// Suggested Fallback Font for Windows with Microsoft Office
// Open / Convert the Word Document using the conversion options
WordDocument wdoc = new WordDocument("C:/input.doc", options);
// Convert and save as PDF

Read more about the options to embed or not embed fonts.

Converting Word to Images

Once a Word document has been loaded by instantiating the WordDocument class, pages in the document can converted to image files. jOfficeConvert can convert pages to JPEG, PNG and TIFF files.

// Save the first page to a PNG file
wdoc.savePageAsPNG (0, "page0.png", 150);
// Save the entire document as a TIFF file
TIFFOptions options = new TIFFOptions (150, TIFFOptions.TIFF_FAX_GROUP4);
wdoc.saveDocumentAsTIFF ("doc.tif", options);

Print Word Documents

jOfficeConvert can also print Word documents, the WordDocument class provides a number of print methods to allow printing to the default printer, to a named printer, or to prompt the user for the printer.

To print to the default printer, or to print to a named printer, use the following lines of code:

// Print to the default printer
// Print to a named printer
wdoc.print ("my printer");

Distribution and JAR Files

jOfficeConvert is packaged in a single jar file, jofficeconvert.jar that needs to be included in the class path when running an application that uses jOfficeConvert.

jai_imageio.jar – This jar file contains Java’s ImageIO image decoders, including a decoder for JPEG 2000 images.  This is only used when a document contains JPEG 2000 images.

jai_codec.jar – This jar file contains additional image encoders / decoders for ImageIO, it is necessary when saving to TIFF.
