ECW Compression

Shrink Big Data
With Enhanced Compression Wavelet (ECW)

When you compress your imagery into ECW format, the result is a much smaller single file that can be stored, sent, and displayed even on small devices. ECW technology provides exceptional compression, capable of reducing terabyte-sized files to five percent of their original size, while retaining the image’s full visual quality.

• High-performance compressed file format designed specifically for extremely large imagery stores
• Achieves 15:1 compression ratios (94% reduction)
• Fastest compression and decompression (rendering) rates in the industry
• ECW file format is supported across all major image server and storage platforms

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.
