Sigil – Multi-platform EPUB e-book Editor

Sigil is an easy to use, open source, multi-platform WYSIWYG e-book editor. It’s designed to edit books in ePub format.

Sigil provides an advanced editing environment for EPUB books. The main user interface (UI) is built around a tabbed central editing view-space and a Book Browser to the left. You double-click files in the Book Browser with your mouse, and an editing (or display) tab is added to the main pane. These tabs can then be closed, reordered or opened again.

Sigil presents a file-focused editing environment. You can open every XHTML file and edit it in a WYSIWYG manner in the Book View, or edit the code directly in the Code View. You can edit the CSS, XPGT and other files, and view the images one by one.

  • Sports an intuitive graphical user interface.
