Convert Word, PDF, JPG in C++

C++ library allows C++ 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 C++ 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:

for (const auto& fileName : fileNames)
{
    auto input = MakeObject<Document>(fileName);
    // Append the source document to the end of the destination document.
    output->AppendDocument(input, ImportFormatMode::KeepSourceFormatting);
}

output->Save(u"Output.pdf");
