DjVu ('Deja vu') is the Next Generation of Image Compression Technology.

Provides high resolution (at VERY small file size) of existing and electronic documents to be distributed on the Internet.

Compression ratios can achieve 1000:1- which is 5 to 10 times better than existing methods.

DjVu files are typically 10 to 20 times smaller than JPEG and five times smaller than GIF.
