Convert EPUB to MHTML in Java & J2SE Applications

Convert Password Protected EPUB to MHTML

Accurately load and convert documents that are protected with a password within your Java based applications. The file format conversion API also supports rendering remote documents from different sources including S3, Blob, FTP, Stream, URL or a local disk.

Create new instance of Converter class and pass source document path
Instantiate the proper ConvertOptions class e.g. (PdfConvertOptions, WordProcessingConvertOptions, SpreadsheetConvertOptions etc.)
Call convert method of Converter class instance and pass filename for the converted document

Source Document Information Extraction

The documents information extraction feature not only allows getting the basic information about the source document file but it also supports extracting some valuable file-format specific information such as project start and end dates of a Microsoft Project file, any printing restrictions on a PDF document, list of folders enclosed in an Outlook data file etc.

Convert popular document file formats on different operating systems such as Windows, Linux or macOS while using development environments such as NetBeans, IntelliJ IDEA and Eclipse.

Convert Specific Word Pages to PDF in Java

Java document conversion API allows you to choose selected pages from the source document and accurately convert to the supported document format. The code example below shows how to convert the 1st and 4th pages of a Word document to the resultant PDF file.

Create a new instance of Converter class and load input (Word) document
Instantiate the proper ConvertOptions class e.g. (PdfConvertOptions, WordProcessingConvertOptions, SpreadsheetConvertOptions etc)
Set setPages property of the ConvertOptions instance and mention specific page number to be converted
Call convert method of Converter class instance and pass filename (PDF) for the converted document

Caching Converted Document Results

In some cases, the converted document size is bigger and it takes time to be converted. The document conversion library offers the caching feature to efficiently manage such situations and speed up the repetitive conversion process. Enable the ICache interface to work with custom cache implementation using the extension point and control the cache conversion, as you prefer.

The conversion result is saved to the local drive by default but any type of cache storage can be supported by implementing the appropriate interfaces such as Amazon S3, Dropbox, Google Drive, Windows Azure, Reddis or any other.

What is EPUB file format?

The EPUB file format is a free and open standard for digital books and other digital documents. It was developed by the International Digital Publishing Forum (IDPF) to provide a consistent format that can be used across all digital reading devices. EPUB files are based on the Open Packaging Format (OPF) and use a folder structure to contain components such as HTML, attached files, and other resources. EPUB also includes Digital Rights Management (DRM) to protect the files from unauthorized access. EPUB files are designed to be lightweight, compressed and to be reflowable; that is, the text can be adjusted to adjust to the size of a device’s screen. This makes them ideal for mobile devices such as tablets and phones. Furthermore, EPUB files can be read on many popular software e-readers and on most platforms such as Windows, macOS, iOS, Android and Linux. EPUB files contain rich, dynamic interactions and can include tables and diagrams, embedded media, footnotes, and more. They are also highly accessible, allowing people with vision impairments to access the text. Overall, the EPUB file format is a convenient, versatile and accessible way to read digital books and documents, making it an ideal choice for digital publishers.

What is MHTML file format?

MHTML, short for MIME HTML, is a web page archive file format used to save and archive web content for offline viewing. It is a combination of HTML code, embedded images, and other external content saved as a single file. MHTML files can be opened with web browsers, text editors, and other programs that support HTML viewing. MHTML files are commonly used to backup websites, share web page content, or email static web page content without the need for an internet connection. The ability to compress everything into a single file makes MHTML files ideal for saving and sharing web content. Additionally, MHTML files are also easier to manage than HTML files as they contain all of the necessary components for viewing in one file. MHTML files are different than HTML files as the MHTML format includes external content. It also uses MIME encoding which allows it to include binary data such as images, audio, and even video files. MHTML files can also be used to print or save web pages for offline viewing, as the file format contains all of the components for viewing. All major web browsers such as Internet Explorer, Firefox, Safari, and Chrome support MHTML files and can open them in their respective programs. Other programs such as Adobe Acrobat Reader and Apple Notes can also open MHTML files.
