Epub vs Mobi: 3 Powerful Website to Convert Epub to Mobi

Epub to Mobi Converter is one of the major resources that authors are searching for online. However, is Epub to Mobi a better format? Well, there’s no doubt that the best e-book format to use in publishing your book is ePub. And just because it’s the best e-book format to use, that doesn’t mean it is the only one you’ll have to use. Now, here’s why;

EPub files do not work on Amazon Kindle services. Instead, Amazon is said to use a proprietary format called AZW3, which is formerly called MOBI.

This is essential because, as you have guessed, Amazon is said to be the largest retailer of e-books. They are known to sell about eighty percent of digital books worldwide.

Two main reasons you might want to convert the Epub file to AZW3/MOBI. 

  1. To publish your book via Kindle Direct Publishing, which is said to permit readers to purchase it on Amazon and go ahead to read it on their Kindle device.
  2. To send your book directly to someone who desires to have a look at it on Kindle Unlimited.

In either way, you’ll have to use Amazon’s e-book converter and the Kindle previewer. Not only does this tool convert your ePub file into AZW3 or MOBI format, but it is said to show how it looks on various devices.

For this post, I’ll explain the differences between all e-book files, and I’ll dive into how to convert Epub to Mobi.

 Epub to Mobi Converter

The standard file format for all e-books is ePub. The ePub format is free, open-source, and based on HTML and CSS, which are all the standard languages for web code. It means its widely and easily accessible to all users alike.

In addition to that,  the Digital Publishing Forum (IDPF) has issued standards to ensure ePub books look pretty nice on all platforms.

Epub files are said to function on various e-book apps and readers, including Apple books, Sony e-readers, and Kobo. Of course, there is a caveat, too; each retailer adds its standards to the IDPF’s needs, which can very well make things a bit complex. But generally speaking, ePub is the general e-book format.

And one of the retailers that don’t support ePub is Amazon. Instead, they are known to use a proprietary AZW, AZW3file, and MOBI.

AZW3, also known as format eight, was released to the public in 2011, and it is the newest Amazon e-book format. As for AZW and MOBI, they are said to be older types. Nonetheless, the kindle app and all kindle devices are known to support these file types.

You might want to say this is becoming too technical. Still, you have to know that this has to be stated out because much of these technicalities cause huge problems in the long run.

For example, you have a book, and you desire to transfer it to someone’s Kindle. This process is known as ‘side-loading. It’s more or less a system that uploads and downloads, and instead of going through the web, you transfer content between both devices. In this case, you might be deemed to use a USB cable, WI-FI or Bluetooth.

What is an Epub? Its full meaning means ‘electronic publishing,’ an open standard, free, open-source file format based on XML, CSS, and XML. It is said to be the universal gold standard for all types of book publishing. Unlike MOBIs, Epub books are said to be read by various devices, including Sony e-readers and Android devices. The International Digital Publishing Forum created an epub in the year 2007, which replaced the OEBPS.

What is MOBI? MOBI files are simply a file extension created for e-books but strictly on Amazon. Mobile e-books are said to use XHTML and do include Java-script. MOBIs are said to be in a larger file size than Epubs. The name is said to come from the company Mobi-pocket reader, which Amazon-owned from 2005-2016; at this point, Amazon had to shut it down.
