STDU Viewer for Windows

STDU Viewer is a free program for reading electronic documents. The main feature of the application is a wide list of supported formats: FB2, DjVu, PDF, Comic Book Archive (CBR or CBZ), PDB), MOBI, AZW, EPub, XPS, TCR, multipage TIFF, TXT, DCX, WWF, PCX, JBIG2, EMF, WMF, BMP, GIF, JPG, JPEG, PNG, PSD.

Allows you to view multiple documents in a single window, and displays page thumbnails of the document in the sidebar. Separate searchable tabs are provided for reading several books, and the bookmarks system allows one to go back to the last page read at any moment.

There is a possibility of scaling pages, simultaneous display of several pages on the screen, rotation of pages by 90 degrees, setting brightness, contrast, and gamma of the document display, adding bookmarks, for quick search of important text fragments, and document printing.

To display text documents the font, size, color, and paragraph display rules are specified in the application settings. Also, there is an opportunity to save DjVu in a text file (if the OCR layer is embedded) of the whole document or particular pages, specifying their numbers, as well as converting DjVu to other graphic formats: BMP, gif, jpeg, and png.
