ECW Overview

ECW Capabilities

Visually Lossless Compression

Wavelet compression algorithm achieves 15:1 compression ratios at a visually lossless quality level.

Fastest Compression and Decompression

ECW compression is at least 50% faster at compressing images than other compression techniques.


Software developers can enable rapid and efficient file handling in their applications using ERDAS ECW/JP2 SDK.
