BMP is an image file that stores raster graphics. BMP format does not use compression an thus high-resolution images saved as BMP images are larger than files saved in other comparable formats. BMP is capable of storing images in various color depths.
ECW is a proprietary Wavelet compression format optimized for aerial and satellite images developed by Earth Resource Mapping, but now owned by ERDAS. ECW file can hold data gathered with satellite or aerial cameras and georadars located in space.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the BMP file after converting to ECW may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from BMP to ECW to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting BMP to ECW does not meet your expectations, you can simply try to find on the Internet a different version of your file in BMP format, properly converted to a ECW file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file BMP the desired result was not achieved, you can try to change the format of BMP file to other than ECW. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your BMP file converted by someone else, and the attempt to convert it to ECW on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the BMP file in its original format (without conversion to ECW file). Such a solution will be difficult to implement, but it certainly will give the best result.
