What is DjVu and why do you need a DjVu reader for Mac?
DjVu (pronounced "déjà vu") is a file format that was developed in the late 1990s by AT&T Labs as a way to store scanned documents with high compression and quality. It uses a combination of lossy and lossless compression techniques to reduce the file size of images without sacrificing much detail or resolution. It also supports advanced features such as layers, annotations, hyperlinks, metadata, etc.
DjVu files are typically used for digitizing books, magazines, newspapers, manuscripts, maps, etc., that contain a lot of text and graphics. They are also suitable for storing documents that have complex layouts or mixed content types (such as text, images, drawings, formulas, etc.). Some examples of websites that use DjVu files are Internet Archive (archive.org), Project Gutenberg (gutenberg.org), Wikisource (wikisource.org), etc.
However, unlike PDF, which is widely supported by various applications and platforms, DjVu is not so easy to access and manipulate on a Mac. You need a special software that can read and convert DjVu files on your Mac. Otherwise, you will not be able to view the content of the files, or you will have to use online converters that may compromise the quality or security of your files.
That is why you need a DjVu reader for Mac, such as Djvureader Ex for Mac, which is a fully featured reader and converter for DjVu files on Mac OS. It allows you to open, view, print, search, bookmark, extract images, rotate, and convert your DjVu files to other formats with ease and speed.
