Convert CAL to BMP

Understanding CAL and BMP file formats

CAL (CALS Raster) is a bitmap image format developed by the U.S. Department of Defense for document imaging. It is commonly used for storing monochrome (black and white) images, especially in engineering and technical documentation. CAL files are not widely supported by mainstream image viewers.

BMP (Bitmap Image File) is a standard raster graphics image format used to store bitmap digital images, especially on Windows platforms. BMP files are widely supported and can store images in various color depths.

Why convert CAL to BMP?

Converting CAL to BMP allows for easier viewing, editing, and sharing of images, as BMP is compatible with most image editors and viewers. This is especially useful if you need to work with CAL images outside of specialized environments.
