SumatraPDF – Small and fast multi-format universal eBook reader

Software's size and function are growing with each passing day, yet those small ones are always welcome by users. Foxit Reader and PDF-XChange Viewer have taken over the market of the bulky Adobe Reader at one time, but they also gradually lost the original lightsome look in the process of commercialization. In this trend, only SumatraPDF is still faithful to its original faith!
