Combine DOCX to PDF using C++ REST API

Easily merge DOCX to PDF format in C++ code. This C++ library is designed to combine multiple DOCX files into a single PDF file using the REST API, i.e. by passing HTTPS calls over the Internet.

This is a professional Cloud-native DOCX to PDF merging solution that provides C++ programmers with both great development flexibility and powerful features. Joining DOCX files together is often used when it is necessary to create a set of PDF documents of the same structure, each of which contains unique data. By merging files, you can automate your digital DOCX/PDF workflows and offload some routine parts of the process to fast and efficient document-processing C++ software.

Merge several DOCX into one PDF in C++

You may need to combine DOCX files into a single PDF file in many cases. For example, you may want to combine multiple DOCX files together before printing or archiving.

DOCX merging can be part of a whole integrated document-processing approach for generating PDF documents from disparate data sources. Such tasks involve the use of a full-featured DOCX/PDF manipulation C++ library that will process a set of DOCX files and merge them together in the shortest possible time, producing a compact and accurate PDF result.

Merge DOCX to PDF in C++

To perform DOCX to PDF merging in C++, you need at least two source DOCX files. For a quick start, please check out the C++ code example below.

);

How to merge DOCX to PDF C++ REST API

  1. Install C++ SDK and add the reference (import the library) to your C++ project.
  2. Open the source DOCX file in C++.
  3. Load a document to append from the Cloud storage.
  4. Call the appendDocumentOnline() method, passing the output filename with the required extension.
  5. Get the combined result in PDF format as a single file.
