C++ API to Export EPUB to MHTML
Render EPUB to MHTML within C++ applications without requiring any third party application
Why to Convert EPUB to MHTML?
The EPUB file format is a popular format for e-books, which is widely used for digital publications. It is an open standard format that is supported by many e-book readers. However, the MHTML format is a web page archive format that is used to store web pages and other related content. It is a more versatile format that can be used to store web pages, images, audio, and other multimedia content. Therefore, it is often necessary to convert EPUB files to MHTML in order to make them more accessible and easier to share.

C++ API to Render EPUB to MHTML
Get Started with C++ File Automation APIs
Install from command line as nuget install Aspose.Total.Cpp or via Package Manager Console of Visual Studio with Install-Package Aspose.Total.Cpp.
Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .
// load EPUB file with an instance of Document class reference
auto doc = MakeObject<Document>(u"sourceFile.epub");
// save EPUB as a DOC
doc->Save(u"DocOutput.doc", SaveFormat::Doc);
// load DOC with an instance of Document
System::SharedPtr<Document> wordDoc = System::MakeObject<Document>(u"DocOutput.doc");
// save document as Mhtml
wordDoc->Save(u"output.Mhtml");
Change Password of EPUB Document via C++
In the process of rendering EPUB to MHTML, you can open a password protected EPUB and also change its password. In order to change the password of a EPUB file, you must know the owner password of that document. You can load password protected PDF document with Aspose.PDF for C++ by specifying its owner password and use ChangePasswords method to change the password.
// load an existing EPUB Document
auto doc = MakeObject<Document>(L"input.epub", L"owner");
// change password of EPUB Document
doc->ChangePasswords(L"owner", L"newuser", L"newuser");
// save the document
doc->Save(L"output.Doc");
Restrict MHTML File Editing via C++
You can also restrict MHTML file editing using using Aspose.Words for C++ API. Sometimes you may need to limit the ability to edit a document and only allow certain actions with it. API enables you to control the way you restrict the content using the ProtectionType enumeration parameter. The following code example demonstrates how to restrict editing in a document so only editing in form fields is possible.
// load Doc with an instance of Document
auto doc = System::MakeObject<Document>("input.doc");
// document protection only works when document protection is turned and only editing in form fields is allowed.
doc->Protect(ProtectionType::AllowOnlyFormFields, u"password");
// save the protected document.
doc->Save(u"Protected.Mhtml");

What is EPUB File Format?
An EPUB file, also known as an Open eBook File, is a standardized format developed by the International Digital Publishing Forum (IDPF). It is based on XML (eXtensible Markup Language) and XHTML (eXtensible Hypertext Markup Language). EPUB files are designed for reading digital books and publications on various electronic devices such as e-readers, tablets, and smartphones.
EPUB files consist of three main components. The first component is the spine, which contains the main text of the book and defines the order in which the pages should be read. It provides the structural framework for the content.
The second component is the manifest, which serves as a catalog of all the files that make up the EPUB book. This includes the spine, cover image, table of contents, and any additional content. The manifest ensures that all the necessary files are properly linked and organized within the EPUB package.
The third component is the container, which stores the EPUB files in a compressed format. The container helps reduce file size and enables efficient distribution and storage of EPUB books.
EPUB files can be created using various software programs such as Adobe InDesign, Sigil, and Calibre. These tools provide authors and publishers with the ability to create, edit, and format EPUB books according to the specifications set by the IDPF. With EPUB being an open and widely adopted standard, readers can enjoy a seamless reading experience across different devices and platforms.
What is MHTML File Format?
MHTML, short for MIME HTML, is a file format that combines HTML code and its associated resources into a single file. It stands for Multipurpose Internet Mail Extension HTML. MHTML files are commonly used for saving web pages, including all their content such as images, CSS stylesheets, and JavaScript, into a single file.
MHTML files are often created by web browsers when users save web pages for offline viewing or archiving purposes. By bundling all the necessary resources into one file, MHTML ensures that the web page can be viewed and rendered accurately, even without an internet connection or access to the original server.
The MHTML format follows the MIME standard, which is used for encoding and exchanging various types of data over the internet. It uses multipart MIME encoding to package the HTML code and associated resources into a single file. The file typically has a .mht or .mhtml file extension.
MHTML files can be opened and viewed by web browsers that support the format, such as Internet Explorer, Microsoft Edge, and Opera. Some text editors and specialized software also provide the ability to open and edit MHTML files.
The MHTML format offers advantages in terms of portability and convenience, as it allows users to save and share web pages as a single file, ensuring the preservation of the page’s layout, formatting, and linked resources. However, it’s worth noting that MHTML is not as widely used as other web formats like HTML or PDF, and compatibility may vary across different software and platforms.
