How To Easily Convert Word To Mobi Or Epub Files

Convert Word Doc To Epub Or Mobi

It’s very easy to learn how to convert Word to mobi and epub. But why do you need to convert your Word document?

Most ebook reading devices use the epub format. But the mobi ebook format, or Kindle book format, is the only file type that can be read on Kindle devices and Kindle apps.

Converting is the only way that you can check and make sure that you correctly formatted your Microsoft Word document for ebook reading.

You need to do this before you upload your manuscript to a self-publishing service such as Amazon KDP, Smashwords, or Draft2Digital.

How to prepare your manuscript

Converting and checking your Word document and ebook formatting on your Kindle, iPad, or PC is vital.

When you convert Word to Kindle mobi format, you can see if there are any formatting errors in your docx or doc file. It’s always better to do this before you publish your ebook and it goes on sale.

Poorly formatted ebooks are a sales killer. So you really should take the time to learn how to check your ebook well before you publish it.

But before you start converting Word docx to epub or mobi, make sure your Word document is correctly formatted using Word Styles.

Good formatting in your Word document will make your ebook look and read much better for your potential ebook readers.

The most important formatting element is to make sure you use Heading 2 for your chapter titles. By doing this, your table of contents will be automatically created in your ebook.

You should use Hearing 1 for your book title, and normal for your text.


Check for mistakes

You should also perform a thorough grammar and spell-check. Grammarly is highly recommended as a grammar correction tool.

But for authors, Prowritingaid is the preferred writing tool because it works so effectively when analyzing long documents such as a book manuscript.

Either tool will help ensure that your manuscript is as error-free as possible before you start proofreading your ebook.

Now you are ready to convert either Word doc to epub format, or Word docx or doc to mobi Kindle format.

Don’t worry if you are not technically minded.

The conversion process from Word to mobi or epub is very easy, and you don’t need any special computer skills at all.


How to convert a file from Word to mobi or epub file format

The first step is to download a free software program called Calibre. It is a free open source program available for both PC and Mac.

Calibre comes with many features which you can learn about later. But as Word to a mobi and epub converter, it is one of the easiest and quickest tools to use.

How to convert a file from Word to mobi or epub file with Calibre

Once you install Calibre, there are two basic ways you can add your Word file.

The easiest way is to use your Word docx file.

If your manuscript is in the old doc format, all you need to do is do a save as in docx. This will create a new copy of your manuscript that you can now use.

The second way is to save your Word document in .html.

To do this, click on “save as” and then select the file type as .htm.

If you know how to edit HTML, this is the best time to clean up your HTML file before file converting.

But if you are new to ebook creation, you should use the Word .docx file type. It is much quicker and easier to convert.

But remember, if your Word document is in doc format, simply do a “save as” in .docx before you upload your file to Calibre.


Preparing for the conversion from Word to mobi and epub

Once you have your Word docx file saved and ready, go to Calibre and click on ‘Add Book’ to select your book’s Word file.

You will then have both epub and mobi files in your Calibre library.

It is so easy to convert Word doc to mobi or epub, or from epub to mobi.

    What a life & time saver?

    I have just run a test with some large documents, publications, and books. It is an easy way to check all the work I edit before forwarding to anyone. Thank you for this.

    You are awesome! Nothing was working until I read this. I copied my pc word file to my wife’s mac, opened with Pages and exported as an epub and bangorang! it worked beautifully.
    I emailed the epub to myself, opened with my ipad and save as an ibook. Everything looks great; except the cover. Now I just need to figure out how to add the cover art. Perhaps that’s an iTunes Producer function.

      You can add a cover very easily by using Calibre. Just import your epub file, add you cover and export it again in epub.

    Thanks so much for this article. I’m having a problem where I have a map of the world I’ve created in the front of my Word doc. When I use Calibre to convert it to Mobi, the Mobi doc recognizes the map as my cover. When I go in to add the “true” cover, the map disappears. How can I avoid this? Thank you!
