Epub Editing Software

If you’re like me, you write ebooks. Or maybe the term “ebook” doesn’t mean much to you yet. In any case, you need to know about editing software for ebooks—specifically what I’ve found to be the best of its kind: Sigil.

epub cover editor

EPUB and MOBI are the most common formats for reading eBooks on eReader devices and tablets. Apple’s iBooks, Barnes & Noble’s Nook, Adobe Digital Editions, and Aldiko on Android all support EPUB. Amazon’s Kindle uses MOBI, a software package created by the French company Mobipocket, which was bought by Amazon in 2005. MOBI eBook files usually have the .prc or .mobi extension.

The advantage of EPUB and MOBI is that both formats display reflowable content (the text adjusts to fit the size of the screen on your reading device) as well as fixed-width layout. Both formats are also open standard, which means that they are free and publicly available, although rules exist regarding their usage.

EPUB and MOBI files can be edited using a number of eBook editing tools. MOBI should first be converted to EPUB, after which the file can then be edited using one of the tools described in this guide. A variety of MOBI to EPUB conversion tools are freely available online. CNET.com lists many of these tools with crowdsourced reviews.

Editing an EPUB

An EPUB is essentially a ZIP file containing nested folders with XHTML text, images, Cascading Style Sheets (CSS), embedded fonts, and metadata files. Almost anyone can edit EPUB files with the help of an eBook editing tool, although some familiarity with hypertext markup language (HTML) is helpful.

Sigil and calibre are open source software applications that can be downloaded freely from the Web. Both are maintained by volunteer developers, which means that user support is limited. The user instructions provided below are very basic. The best source for help is usually one of the online forums where users exchange information and answer questions.

2. Calibre

Calibre is a free and open-source e-book computer software application suite which is available for Windows, Linux, and iOS, allows users to manage e-book collections as well as to create, edit, and read e-books. This eBook creator has almost all the advanced features that you need to make your own eBook.

Besides this, an inbuilt eBook cover creator is an added advantage to Calibre which helps you create customized cover picture to your eBook.

3. Sigil

Sigil is a free, open-source application that will allow you to import and edit ebooks in .TXT, .HTML and .EPUB format, and only convert them to .EPUB format for export. Sigil has a number of nice functions that make editing much easier, like exploit audio, video, images within your eBook and tweak words by superscript, subscript, strikethrough, tables, lists, hyperlinks etc. Although there are ebook editors out there with more functions, not all of them are this pleasant to use. If you are happy with a basic range of features for your epub editor, Sigil is the one for you. But we have to admit that Sigil’s only disadvantage is that it can’t support many formats.

how to edit a epub file

There are several great programs available to help you design a high quality cover image for your ebook. Programs like Photoshop are great, but you don’t need any expensive design programs to make a great ebook cover. There are lots of free design tools available. Here is one of our favorites. Its called CANVA, its easy to use and its totally free.

2. Click “Create a Design”

3. Then choose the “Kindle Cover” option under “Blogging & eBooks”. You can also choose “eBook” either of these options will produce a high quality image perfectly sized for your ebook, but the Kindle option has more free layouts to choose from. The 1410px by 2250px image will be just the right dimensions for your Kindle and most other ebook devices.

4. Select one of the free design options (there are also paid options. but the free layouts are great, and you can use the paid layouts for inspiration when you customize your own cover!)

5. Use the editing features to customize the images and text on your cover. If you want to add an image to your cover (maybe as the background) check out Pexels.com Its a great place to find images that are 100% free to use.

6. When you are done, simply click the “Download” button to produce a high quality PNG or JPG image for uploading to Amazon and Apple.

NOTE* You can actually use Canva to create an entire PDF ebook. But keep in mind, this is NOT the same thing as an epub ebook. Epub is an ebook format that can be sold on Apple, Amazon and other ebook stores, and a PDF is not. An ePub (or Mobi) file is also a flowing text format, which means the content will adjust to fit the size of the device. A PDF is non-responsive, and will not change depending on the device size. So PDF files can be very difficult to read on tablets and especially on small devices like an iPhone.
