Do you write ebooks, but struggle with messy EPUB files that break on readers? This sigil download for pc guide shows you how to get a free EPUB editor on Windows, how to install it on Windows 10 and Windows 11, and how to edit your first ebook. It gives you a clean book view and a code view, and it costs nothing to use.
What Is Sigil?
Sigil is a free and open-source ebook editor for the EPUB format, used by authors and publishers. It lets you create an EPUB from scratch, or open an existing one and fix its text, styles, images, and metadata. The main window shows the book as a reader sees it, while a code view shows the HTML underneath for precise edits.
The editor also builds the table of contents, checks the book for EPUB errors, and manages the files inside the ebook package. That mix of visual editing and direct code access suits both beginners and technical users. For self-published authors, it is the standard free tool for producing a clean, valid EPUB.
