Sigil 1.8.0 for Mac – Download

Sigil is an open source eBook editor that works with GPLv3.

Editing with Sigil follows the WYSIWYG principle (what you see is what you get) and works almost identically to other word processors like Microsoft Office.

Currently, Sigil can import files in TXT, HTML and EPUB formats and export to EPUB and SGF (Sigil native format).

The program is very easy to use and although it is still in the early stages of development, it includes many interesting features for eBook owners.
