CRW to BMP3
File Converter

CRW was one of the early raw image file formats used by Canon digital cameras. It captures all the data from the camera’s sensor without any compression or processing, preserving the maximum amount of image information for post-processing. However, this format has largely been superseded by the newer CR2 and CR3 formats, which provide more advanced features and better compression. CRW files require specialized software for viewing and editing, and they are generally larger in size compared to standard compressed image formats.

BMP3 (Bitmap Image File V3) is an image file format developed by Microsoft, commonly used for storing two-dimensional digital images in a wide range of color depths. While BMP files are capable of storing detailed images without any compression—preserving the original quality—they often result in large file sizes, making them less ideal for web usage or sharing.
