Enhanced Compression Wavelet



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. 

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.



  • High-performance compressed file format designed specifically for large imagery stores.
  • Achieves 15:1 compression ratios – 94% reduction
  • ECW file format is supported across all major image server and storage platforms.
  • Incorporate ECW into your Desktop, Server or mobile application.
  • ECW outperforms all alternative storage formats across these four critical image format characteristics:
    • Encoding speed
    • Decoding speed
    • Retention of the necessary image quality
    • File size reduction



  • Shrink Big Data – Preserve Critical Information while saving space with simple, cost effective and powerful compression for both imagery and point cloud data.
  • Rapid Generation and Delivery – Create ECW files faster than 25MB per second, with delivery benchmarked as the industry’s finest.
  • Huge Disk Space Savings – ECW can compress imagery to 5/10% of original size, while maintaining visual quality.
