SumatraPDF Portable is a lightweight Windows program known for its reader that supports multiple document formats including PDF, ePub, MOBI, XPS, DjVu, CBZ and CBR.
Ultra fast
The app is renowned for its lightning-fast startup and minimal memory footprint. Unlike many feature-heavy analogs, the reader launches almost instantly and remains responsive even with large documents. On top of that, there is a clean, clutter-free interface designed to keep users focused solely on the content. There are no distracting sidebars or bloated menus, only the core viewing tools are presented. It is possible to switch between fullscreen, presentation or book modes.
Shortcuts
Power users can take advantage of extensive keyboard shortcuts to navigate documents, zoom, rotate pages or search without touching the mouse. The utility also supports scripting and advanced command-line options, which allow integration into custom workflows or automation routines.
Similar to Ditto, this is a portable version that can be run directly from a USB stick without installation. All settings and preferences are saved alongside so that you would configure the parameters each time you open the utility in different computers.
