DjVu is a web-centric format and software platform for distributing documents and images.DjVu can advantageously replace PDF, PS, TIFF, JPEG, and GIF fordistributing scanned documents, digital documents, or high-resolutionpictures. DjVu content downloads faster, displays and renders faster, looks nicer on a screen, and consume less client resources than competing formats. DjVu images display instantly and can be smoothly zoomed and panned with no lengthy re-rendering.DjVu is used by hundreds of academic,commercial, governmental, and non-commercial web sites around the world.DjVu is a web-centric format for distributing documents and images. DjVu was created at AT&T Labs-Research and later sold to LizardTech Inc. DjVuLibre is a GPL implementation of DjVu maintained by the original inventors of DjVu. Get a Free Software PDF reader! The Portable Document Format (PDF) is a popular format to publish formatted text and documents. There are several different versions of it, some qualifying as an Open Standard, some certified by ISO and some encumbered by software patents.
DjVuLibre is an open source (GPL'ed) implementation of DjVu, including viewers, browser plugins, decoders, simple encoders, and utilities.
Native plugins for MS Windowsand Mac OS X are freely available from LizardTech Inc.The new portable viewer djview4is available as a separate package.

DjVu (pronounced 'déjà vu') a set of compression technologies,a file format, and a software platform for the delivery over the Web of digital documents, scanned documents, and high resolution images.DjVu documents download and display extremely quickly, and look exactlythe same on all platforms with no compatibility problems due to fonts,colors, etc. DjVu can be seen as a superior alternative toPDF and PostScript for digital documents, to TIFF (and PDF) for scannedbitonal documents, to JPEG and JPEG2000 for photographs and pictures, and to GIF for large palettized images. DjVu is the only Web format that is practical for distributing high-resolution scanned documents in color. No other format comes close. 
Typical DjVu file sizes are as follows:
bitonal scanned documents: 5 to 30KB per page at 300dpi (3 to 10 times smaller than PDF or TIFF)
color scanned documents: 30 to 100KB per page at 300dpi (5 to 10 times smaller than JPEG).
photos: 2 times smaller than JPEG, about the same as JPEG-2000, but the decoder/renderer is progressive and has minimal memory requirements.
palettized images: 2 times smaller than GIF (up to 10 times if it's mostly text).
digital (non scanned) documents: between 1 and 3 times smaller than PDF or gzipped PS (depending on the amount of pictures), but rendering, page flipping, zooming, panning are incomparably faster, and the image quality on screen desplays is much better (antialiased text, etc).
More importantly, all DjVu images render very quickly and can be smoothly zoomed and panned.Pages of a document can be turned instantly, with no annoying delay.DjVu is used by hundreds of academic,commercial, governmental, and non-commercial web sites around the world to distribute scanned documents, digital documents, and high-resolution photos.

A short technical description of DjVu is available here.In short, DjVu is a multipage document format that can use a number of differentcoder/decoders (codecs) to compress the individual chunks that compose animages or a page. In fact, DjVu is really four compression techniques wrapped into one format:
DjVuPhoto (aka IW44): A progressive, wavelet-based lossy compression format for continuous-tone images (i.e. photos and pictures).
DjVuBitonal (aka JB2): A lossless or lossy compression technique for bitonal (black & white) or palettized images that is particularly effective on images with repeated shapes (such as documents images where the same character appears many times in the document).
DjVuDocument: A technique for scanned color document that separates images into a foreground layer that contains the text and line drawings, and a background layer that contains the pictures and background textures. The foreground is encoded with DjVuBitonal and the Background with DjVuPhoto.
BZZ: A general-purpose data compression technique similar to bzip2. Bzz is used to compress searchable text layers and other metadata in DjVu documents.
DjVu can be seen as nicely complementing PNGand MNG (which, unlike DjVu are lossless formats) in the areas of documentimage compression and lossy photo compression. DjVuPhoto is a bit older, butsimilar in spirit to JPEG-2000. It is on a par with JPEG-2000 in terms ofimage quality and file size, but it compares favorably in terms of renderingtime and memory requirements. DjVuBitonal is better than MMR/GroupIV (used byPDF, TIFF, and most fax machines) by about a factor of 3 to 10. It is alsobetter than the emerging standard JBIG2 by about 20%.Windows and Mac versions of the viewer/plug-in, free Windows compressors, and high-end commercial compressors and OCR engines are available from LizardTech Inc.The compressors provided here are slower, produce larger files (sometimeswith lower image quality) than the commercial compressors, but they do the job.

Details of mobi format Mobi format was invented by French company MobiPocket as an ebook format for their MobiPocket Reader application. The company was bought by Amazon and the format was used in Amazon's Kindle. Unfortunately Amazon added DRM to the format, which means that only Amazon's software or devices are able to read ebooks purchased from Amazon. 
Mobi format is a simplified and adapted HTML. There is no official documentation of the format, but it has been reverse-engineered and documented by the citizens of the internet. 
Mobi files usually have .mobi extension. Amazon's eBooks have .azw extension. Because the format was originally designed for Palm Pilot PDAs, they can also have .prc or .pdb extension.
