Thorium Reader is free reading software from EDRLab for Windows, Mac and Linux. It opens every ebook you buy from eBooks.com: DRM-free EPUB and PDF files, and DRM-protected books (.lcpl files) using your Reading Key. You don't need an Adobe or ByteBooks account. Should I choose Thorium Reader or Adobe Digital Editions?

To install Thorium Reader first please check the minimum system requirements to make sure that your computer meets the requirements. You can check the latest minimum requirements, and download the software install file from EDRLab's website here:

Please note: if you are using Linux you should download from the developer's website and not your distribution's Package Manager as it can cause your Reading Key/LCP Passphrase to not be accepted. See this help article for more information.

If you want to install Thorium Reader on a Chromebook it requires some extra steps. Please see this help article for more information.
