The djvu file extension is associated with DjVu file format, an image format designed to store bitmaps of scanned documents, especially those containing text and line drawings.
The format is increasingly important because of its use in the Million Book Project and the One Laptop per Child project.
DjVu typically achieves compression ratios about 5 to 10 times better than existing methods such as JPEG or GIF for color documents, and 3 to 8 times than TIFF for black and white documents.
Scanned full colored pages at 300 DPI can be compressed down to 30 to 100KB files from 25MB.. Black-and-white pages at 300 DPI typically occupy 5 to 30KB when compressed.
This puts the size of high-quality scanned pages on par with an average HTML page (which is typically around 50KB).
This format can also occur with djv file extension.
MIME type used for djvu images:
image/vnd.djvu
The native viewer developed by original authors, DjVuLibre, is available for download at DJVU website.
DJVU bitmap format is widely supported and can be viewed in many popular bitmap viewers such as XnView, IrfanView or ACDSee.
Most of bitmap viewers support conversions from DJVU to other image formats (JPG, TIFF, BMP, GIF, TGA etc.).
