.EPUB is a common format for ebooks, so Sigil is a relevant player in today's ebook world. The interface is extremely clean and clear to read and it's completely free, so you can't get much better than that. You can also import and edit books that come in a variety of other formats, such as .HTML and .TXT. Once you've edited them in these formats, you can easily convert them to .EPUB format and use them.

Tabs are the name of the game with Sigil. The multiple views provided make Sigil one of the easiest programs of this sort to use. Some views include "Book browser," "Code view," and "WYSIWYG" for final preview of your product.

Functions are rich and advanced to make editing easier. For example, the table of contents editor gives you many options to determine how you want the table of contents to read. This helpful feature gives book editors the freedom to customize everything about the look and feel of the ebook.

If you write ebooks for a living, or if you work for a company looking for a better ebook editor, Sigil is a great option to consider. It's completely free to download, and this fact alone means you can try out this great program risk-free.

Pros
