## Description

ePub Viewer is a versatile Chrome extension designed for easy reading of ePub and OPF files directly within the browser. Utilizing a clean "Reader View" interface, it allows users to comfortably read eBooks without installing additional software. Features include three customizable color themes — light, dark, and sepia — along with adjustable font sizes and families accessed via an intuitive side panel.

The extension supports smooth navigation through an embedded table of contents, enabling users to jump between chapters effortlessly. It also remembers your last reading position and encodes it in the address bar, letting you resume reading anytime by reopening the URL. Additional capabilities include full-screen mode for distraction-free reading, the ability to convert ePubs to PDFs, text-to-speech functionality, and loading books from local files. The current version enhances usability by showing loading progress percentages, making ePub Viewer an essential tool for eBook enthusiasts.
