About ECW files

The .ecw file format primarily stores an Enhanced Compression Wavelet image. Developed originally by [Earth Resource Mapping] and now owned by Hexagon Geospatial, it is designed to handle massive aerial, satellite, and geospatial imagery. The format utilizes a proprietary wavelet compression algorithm that allows GIS software to extract specific map regions instantly without loading the entire terabyte-sized file into computer memory.

You can open these files natively using specialized GIS applications like ERDAS IMAGINE, QGIS, or ArcGIS Pro via plugins. For technical details, see the Wikipedia page on ECW.

Despite its efficiency in the GIS industry, the .ecw format is highly proprietary and extremely restrictive outside professional environments. Standard image viewers, web browsers, and graphic design tools completely lack the necessary codecs to read it. Furthermore, encoding new .ecw files requires expensive licensing, and many open-source decoders struggle to parse the newer ECW v3 format. If you need to share a map with a client or display it on a website, the file is practically useless in its current state.

To make the image accessible, you must convert it. For archiving or importing into other mapping software where coordinate data is critical, convert to TIF (specifically GeoTIFF). For web sharing, email, or presentations, convert to JPG or PNG, keeping in mind that geospatial metadata will be lost. Drop your file here to view and convert it securely right in your browser.

FAQ

If you want to convert ECW file to TIFF, JPG, JPEG, DWG, PDF, KMZ, KML, EXE, ISO, BIN, CUE or PAK, you can use ERDAS IMAGINE or similar software from the "Geospatial Raster Image Storage" category. In the File menu, look for Save As… or Export….

To convert MOD, BIN, CFG, SCX, DAT, MPQ, LOG, CUE, INI, EXE, SCM or ISO files to ECW, try ERDAS IMAGINE or another comparable tool in the "Geospatial Raster Image Storage" category.



The ECW Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ECW converter.
