About the DjVu format
DjVu is a very popular image compression technology developed for storing scanned documents-books, magazines, manuscripts, etc. - where formulas, diagrams, drawings, and handwritten characters are very present, making their full recognition extremely labor-intensive.DjVu was developed between 1996 and 2001 and represents a very good mix of all test and image formats.
This compression format is the most effective option for storing documents if there is a need to convey all the nuances of design, for example, historical documents, where the important thing is not only the content, but also the color and texture of the paper; defects in parchment: cracks, traces of folding; corrections, blotches, fingerprints; traces left by other objects, etc. DjVu format saves scanned documents in a smaller volume than scanned documents saved in PDF format. This is especially true for large e-books and textbooks, the version of which in PDF format can take up tens of megabytes, and if you convert PDF to DjVu, you get an excellent e-book with high image quality and a volume of only a few megabytes. A DjVu file is compressed to a small size, which in turn makes it convenient for transmitting and sharing over the network.
