Read or view EPUB files online, no software needed
EPUB Reader Online is a free EPUB reader and viewer that runs entirely inside your web browser. Drop a .epub file onto the page and it opens instantly with a clickable table of contents, dark reading mode and keyboard navigation. There is nothing to download or install, so it works on Windows, macOS, Linux, Chromebook, Android and iPhone alike.
Unlike most online EPUB readers, this one never uploads your book. The file is unpacked and rendered locally using JavaScript, which means it is fast, private and works with books of any size. Your reading position is remembered on this device, so you can pick up where you left off the next time you open the same book.
