Simple document viewer for PDF, XPS, CBR and more

STDU Viewer is a free file viewer that deals specifically with the most important scientific and technical documentation formats – namely TIFF, PDF, DjVu, XPS, JBIG2, and WWF.

This app also supports other formats, but don’t rely on it for everything – you can’t open things like .DOC or .HTML, for example – but you can get quite far with lots of image file support as well as “comic” formats, like CBR and CBZ.

STDU Viewer features the traditional viewer interface: a main area to display the selected page and a sidebar to show content summary. There’s also a bottom bar with handy navigational controls; and a top menu bar to access tools, like zoom, text selection and page adjustments.

STDU Viewer can open several documents simultaneously and is light on system resources. If it had support for those missing formats, it would be the perfect document viewer! There is also a portable version of STDU Viewer, for users who are constantly on the go.

STDU Viewer is the perfect viewer for technical documentation and more.
