This EDRLab application is in constant development and aims at becoming a reference for accessing EPUB 3 publications in reflow or fixed layout format, visual narratives (DiViNa), audiobooks and even LCP protected PDF documents.

Huge efforts are made to get Thorium Reader highly accessible for visually impaired and dyslexic people.

This application is free, with no ads and no leaks of private data.

Please Donate for Thorium Reader

The application is 100% free for its users, but its development is costly for a non-profit development laboratory. We believe that the companies which deploy Thorium Reader and the publishers which want a real alternative to proprietary solutions should help developing and maintaining this application.

You can help us financially, as a “one-shot”, by offering 1000 € to EDRLab for the development of the next features.

Why developing Thorium Reader?

Until now there was no modern EPUB 3 compliant reading application usable on Windows, OSX and Linux, properly accessible for print disabled people, with a good support for the LCP DRM and capable of browsing OPDS catalogs.

EDRLab decided to build such an application and release it for free, in order to provide users a great way to enjoy on a large screen EPUB publications, comics / manga / bandes dessinées, audiobooks, LCP protected PDF documents.

Print disabled people now benefit from an EPUB 3 reading app which supports screen readers like Jaws and NVDA on Windows, Voice Over on Mac.

Technology

Thorium Reader is based on the set of open-source chrome-less modules, a toolkit named Readium Desktop. Thorium Reader and Readium Desktop both rely on Electron.js, node.js and typescript, which are efficient cross-platform technologies. Thorium is also using React components based on HTML 5/CSS 3.
