A powerful WYSIWYG editor

The Sigil interface can be a bit overwhelming at first, as you'll see several dozen different icons with many shortcuts to different features and tools. However, most of the program's features are very intuitive, and you can read their explanations by simply hovering the cursor over its icon. In any case, the most useful part is that everything you do in its WYSIWYG editor is instantly reflected in the final preview of the document, which can normally be seen on the right of the screen. Additionally, you can press the F1 button to quickly access all the software documentation, with tutorials and tips to get you started with the app.

Edit text and metadata as you see fit

Thanks to Sigil, you can easily edit any aspect of an EPUB file on your PC. As soon as you load the file in the program, you'll see a breakdown of all its elements in the left column: text, style, fonts and images. Within each of these folders are several elements that you can edit and customize as you wish. For example, in the font folder, you can easily replace fonts to give any book a completely new look. Similarly, in the text folder, you can edit the content on any of the document's pages, adding and removing whatever you like.
