Welcome again to the Home of File Format APIs! In the recent past, I have written a couple of blog posts to cover various scenarios of converting Word (DOC/DOCX) to PDF programmatically in .NET (using C#) and Java applications. Since this is a popular and widely used feature, I thought to cover it for C++ as well. Therefore, in this post, I will show you how to convert Word DOC/DOCX to PDF in C++ applications. This article addresses the following Word to PDF conversions:
- Simple Word DOC/DOCX to PDF in C++.
- DOCX to PDF with particular standard i.e. PDF 1.5, PDF/A-1a, etc.
- Converting selected pages of a DOCX to PDF.
- Apply image/text compression in DOCX to PDF conversion.

You may also convert only the selected pages instead of converting the whole Word to PDF. The following are the steps to convert only the desired pages of Word to PDF:
- Load the Word document using Document class.
- Set the starting page’s index using PdfSaveOptions->set_PageIndex() method.
- Set the number of pages you want to convert using PdfSaveOptions->set_PageCount() method.
- Save the document as PDF using Document->Save() method.
The following code sample shows how to convert selected pages of DOCX to PDF in C++.
Apply Image/Text Compression in DOCX to PDF Conversion
You may also compress the resultant PDF document in order to reduce its size. Aspose.Words for C++ lets you apply the text and image compression using PdfSaveOptions->set_TextCompression() and PdfSaveOptions->set_ImageCompression() methods respectively.
