The ePUB format is an extension format intended for the use of electronic books, called e-books, they can be purchased or downloaded through Internet sites, and read through devices or computers. However, you can also create an ePUB file with HTML and XML from scratch yourself.
Although this is not the only format in which one of these files can be acquired, since the most popular is PDF, it turns out to be the most recommended and used due to its characteristics of improving their readability.
That is why, from a technological point of view, ways have been innovated so that various extensions can be converted to ePUB , and thus comfortably enjoy the book.
For those who want to create ePUB files, they should know that one of the methods to achieve it is through HTML and XML. Therefore, it is your lucky day if you have knowledge about this programming language.
If not, you should not worry either, because in this article we will explain how to form this type of extension for electronic books from scratch.
Start creating your ePUB book by writing through HTML
Although their main use is for programmatic purposes, HTML format files are nothing more than text sheets, styled for aesthetic purposes when viewed in a browser; even, the transcription of this language can be done from Word , and then achieve a conversion.
Therefore, proceed to write your book in its entirety, or divided into chapters, through the text editor, and then form their respective style sheets in number of two: the first dedicated to the pages, and the other to the style of the whole book in general.
Then, open a new document inside your editor, and write inside the sheet “application / ePUB + zip”, then save as “mimetype” without any extension.
Assigning them the name you want, and with the appropriate extension, save all the files within the same folder on your computer.
Design the first look at your book
Both the cover and the title page will be the main attraction for readers, including the synapse of your book, so it is very important to assign both aspects in the most appropriate way possible.
For the cover you must store an image whose weight is not greater than 64 kB, and that has a “JPG” format. This must be legible enough so as not to cause visual difficulty for readers.
On the other hand, the title page must have its own file with an “XHTML” extension, which can contain an image or simply text, depending on the editor’s taste.
Create the respective XML files of your ePUB
Each one being designed within the text editor you are using, they are the ones who will assign meaning and link to the HTML content that makes up your ePUB extension file .
The first of all will be the index, designated in any way, but with the extension “NCX”. In your content, you must generate a link to each of the HTML files that are inside the folder.
The second is a file called “container.xml “, which is a container that you must keep in a subdirectory, in the book folder.
Finally, a file will be generated with the name and extension of “ content.opf ”, which will be in charge of storing the information about the author, the genre of the book and other metadata.
Compress the book directory
Through any program, such as WinRAR, select the folder of the book to compress it through the software, with the only difference that instead of acquiring the extension of “ZIP”, you must change it to “ePUB”.
Once the process is finished and the reading and viewing has been successfully tested, you can attach it to the Internet so that anyone interested can download it and enjoy its content.
Creating an ePUB file with HTML and XML from scratch is not that simple, but with hours of effort and dedication, you will generate content that the community will like.
