Sigil Ebook 2.4.2
Sigil: The Ultimate EPUB Editor for Book Creators
Sigil is not an eBook reader—it’s an EPUB editor. That means you use it to create, edit, and format eBooks. This free and open-source EPUB editor lets you craft professional-quality eBooks with ease, whether you’re a self-publishing author, an editor, or just someone who wants their personal library to look perfect. Sigil is an Open Source multi-platform WYSIWYG eBook editor. Portable version is also available.
Why Use Sigil?
With Sigil, you can write an eBook from scratch, typing directly in its editor and formatting your text just like in a word processor. If you have an existing EPUB, you can edit it with ease, tweaking the layout, fixing typos, or refining the formatting. Sigil also allows you to convert and clean up documents, importing TXT or HTML files and transforming them into polished eBooks. You can customize metadata, adjusting details like the book title, author, and publisher information, ensuring everything is properly organized. Creating a Table of Contents is seamless, letting you design a structured TOC for easy navigation. For those who want even more control, Sigil provides the option to fine-tune EPUBs using HTML and CSS, allowing for advanced customization and precision editing.
Sigil is designed for flexibility and precision, offering both WYSIWYG editing (so you can see exactly how your book will look) and Code View for fine-tuned adjustments. It fully supports EPUB standards, ensuring your books work seamlessly across all major eReaders.
