llpp is a lightweight document viewer built around the MuPDF rendering engine. It supports PDF, EPUB, XPS and CBZ documents, combining fast rendering with a minimal graphical interface.
The application takes inspiration from the less command-line pager. Keyboard shortcuts are central to its design, allowing users to scroll, navigate and adjust document views without relying on extensive menus or toolbars.
llpp uses OpenGL acceleration to display documents and provides options for customising page layouts and viewing behaviour. It supports two-page viewing, annotations and remote control, making it an appealing option for users who want a fast, keyboard-oriented reader.
This is free and open source software.
