Migration Notes

Why To Migrate?

Here are the key reasons to use the new updated API provided by GroupDocs.Conversion for .NET since version 19.9:

  • Converter class introduced as a single entry point to manage the document conversion process to any supported file format (instead of 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 decreased memory usage (from 10% to 400% approx. depending on document type).
  • Document convert options simplified for easy control over document conversion and saving processes.

How To Migrate?

Here is a brief comparison of how to convert 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();

var saveOptions = new GroupDocs.Conversion.Converter.Option.PdfSaveOptions();
saveOptions.ConvertFileType = PdfSaveOptions.PdfFileType.Pdf;
var convertedDocumentPath = conversionHandler.Convert(documentPath , saveOptions);

New coding style

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