Convert Word, PDF, JPG in C#

C# library allows .NET developers to convert Word, PDF and many other file formats. Powerful conversion engine analyses layouts and styles of the original documents, then exports the combined result to the required format.

Document conversions from one format to another may be tricky, unless you have a professional tool to do the job. Use C# to convert Word, PDF, JPG with maximum flexibility and speed. Run online live demo and check the highest quality of conversion right in a browser. DOCX Conversion API supports a bunch of useful options.

Merge Word, PDF, JPG into one file

This is a simple way of converting office documents from one format to another while leaving all the low-level details to Conversion API. C# library enables .NET developers to convert documents in many popular formats with maximum flexibility and efficiency:

  • Microsoft Word: DOCX, DOC, RTF, DOT, DOTM, DOTX, DOCM
  • OpenOffice: ODT, OTT
  • Fixed Layout: PDF, PostScript, XPS, OpenXPS
  • Images: PNG, JPG, GIF, BMP, TIFF, SVG, EMF
  • Web: HTML, MHTML
  • Others: MOBI, EPUB, Xaml, PCL, etc.

Convert multiple documents and save the result as a single file easily. If you develop code in C#, this will be simpler than it sounds. See C# example that iterates through documents and combines them:

Code example in C# to combine multiple files into one
Upload a file you want to merge
Run code
Upload a file you want to merge
Select the target format from the list
dotnet add package Aspose.Words
using Aspose.Words;

var fileNames = new List<string> { "Input1.docx", "Input2.docx" };

var output = new Document();
// Remove all content from the destination document before appending.

foreach (string fileName in fileNames)
    var input = new Document(fileName);
    // Append the source document to the end of the destination document.
    output.AppendDocument(input, ImportFormatMode.KeepSourceFormatting);
