View multiple file formats with STDU Viewer

Everyday we deal with different types of files and use different softwares for viewing those files. Won’t it be a good idea if we can view many such files using a single software? STDU Viewer from Scientific and Technical documentation utility (STDU) was developed with this interest.

  • STDU Viewer can support a number of file types.
  • STDU Viewer has following basic viewing features like: search, quick search, print, rotate document clockwise or anti-clockwise, zoom in and zoom out, fit page, fit width, fit height tools, hand tool, select text tool, select image tool, zoom by selected rectangle etc. It lacks many advanced features like highlight text tool, cross-out text tool, underline text tool, sticky notes tool etc that are present in popular PDF readers. This is quite understandable keeping in mind that it is not only document viewer, its can help viewing other types of files too and such tools will not features may not mean anything in the viewing of most files. So, if you want such features choose PDF viewers of Adobe, Foxit, Nitro, PDF-XChange etc. STDU Viewer can open multiple files in tabs. Unfortunately it doesn’t alert while closing multiple tabs.

My Verdict
I use STDU Viewer mainly to view djvu and djv files. Sometimes I also use it to preview randomly named PDF files in a folder. The software is lightweight and easy to use but is not that complete to replace my PDF Viewers and Image Viewers.
