An EPUB file is one of the most common formats for electronic books (eBooks). Its compact size and ability to store large amounts of written content and images make it an ideal medium for distributing digital books.
EPUB files are actually ZIP files containing standard website files such as HTML, CSS, and images. In fact, you can extract the content of an EPUB file and open it with any standard web browser to view the book content without needing a special ebook reader.
By using standard web formats, EPUB files are easy to create and open and are supported by all the major eBook readers. As they make use of the ZIP file format, they are also very compact and well suited to the task.
All EPUB files contain binary data, with the initial sequence of bytes within the file given up to describe the file and its contents in what is known as the file header. This section of the file contains useful information that our EPUB eBook repair tool can use to help with the repair process.
The EPUB format utilizes the ZIP format as the underlying container for the various pages of the eBook. These pages are stored in XML format, along with the table of contents and any additional media files, such as images.
Our eBook repair tool attempts to seek out the individual eBook content files to perform validation and, if necessary, repair any that seem invalid.
Along with the individual eBook pages, our EPUB repair tool will also look to repair any additional support files, such as the table of contents and the chapter definitions. If there are any additional media files, such as images, these will be processed by our various image repair tools.
