Migration notes

Why migrate?

Here are the key reasons to use the new updated API provided by GroupDocs.Conversion for Java since version 20.2:

  • The Converter class was introduced as a single entry point to manage the document conversion process to any supported file format (instead of the ConversionHander class from previous versions).
  • The overall conversion speed improved dramatically by saving each page as soon as it was converted, not when all pages list were converted.
  • Product architecture was redesigned from scratch in order to decrease memory usage (from 10% to 400% approx. depending on the document type).
  • Document conversion options were simplified for easy control over document conversion and saving processes.

How to migrate?

Here is a brief comparison of how to convert a document into PDF format using old API and new one.

Old coding style

String documentPath = "sample.docx";
String outputPath = "C:\\output\\converted.pdf";

//Instantiating the conversion handler
ConversionHandler conversionHandler = Common.getConversionHandler();

SaveOptions saveOptions = new PdfSaveOptions();
ConvertedDocument convertedDocumentPath = conversionHandler.convert(documentPath , saveOptions);

New coding style

String documentPath = "C:\\sample.docx"; 
String outputPath = "C:\\output\\converted.pdf";
try(Converter converter = new Converter(documentPath))
    PdfConvertOptions convertOptions = new PdfConvertOptions();
    converter.Convert(outputPath, convertOptions);
