Compress PDF in C++

Using our powerful C++ API, developers can compress PDF documents to optimize content and output file size. Reducing PDF size occurs by cleaning up unused data and resources. You can also compress images inside PDF to make the output file size even smaller.

The result of content optimization and compression can be saved in the original PDF or any available save format – DOCX, DOC, RTF, HTML and many others. For example, compress PDF and save the output as Word.

Reduce PDF file size in C++

As mentioned, our C++ SDK allows you to programmatically reduce PDF size. And now you can try our powerful functionality and evaluate how to compress PDF in C++ with the following example:

Upload a file you want to optimize/compress
Run code
Select the target format from the list
using namespace aspose::words::cloud;

auto config = std::make_shared<ApiConfiguration>(L"####-####-####-####-####",
   L"##################");
auto wordsApi = std::make_shared<WordsApi>(config);

auto requestDocument = std::shared_ptr<std::istream>(
   new std::ifstream(std::filesystem::path(L"Input.pdf"), std::istream::binary));
auto requestCompressOptions = std::make_shared<aspose::words::cloud::models::CompressOptions>();
requestCompressOptions->setImagesQuality(std::make_shared<int32_t>(75));
requestCompressOptions->setImagesReduceSizeFactor(std::make_shared<int32_t>(1));
std::shared_ptr<requests::CompressDocumentOnlineRequest> compressDocumentRequest(
    new requests::CompressDocumentOnlineRequest(
        requestDocument, requestCompressOptions
    )
);
auto compressDocument = wordsApi->compressDocumentOnline(compressDocumentRequest);

auto requestDocument = std::shared_ptr<std::istream>(
   compressDocument->document->values.begin, std::istream::binary));
std::shared_ptr<requests::ConvertDocumentRequest> convertDocument(
    new requests::ConvertDocumentRequest(
        requestDocument, std::make_shared<std::wstring>(L"pdf")
    )
);
wordsApi->convertDocument(convertDocument);

How to compress PDF C++ REST API

  1. Install Aspose.Words Cloud for C++
  2. Add a library reference (import the library) to your C++ project
  3. Configure API using your app keys
  4. Load the source PDF to compress
  5. Compress PDF, clean unused information
  6. Select the output file format
  7. Get the result of PDF compression as a separate file

C++ library to use PDF compression

Clone Aspose.Words Cloud SDK for C++ source code from GitHub. You can find detailed information on building and configuring the SDK in the "How to use the SDK" section.
