Convert rad to bmp

What is the difference between .rad and .bmp?

Description: The RAD file format is associated with Radiance, a suite of programs designed for the analysis and visualization of lighting in design. It is primarily used for simulating and predicting the light levels and appearance of a space prior to construction. RAD files contain descriptions of physical materials, geometry, and lighting in a scene, allowing for highly accurate light simulation and rendering. This format is widely used by architects and designers to understand and optimize the lighting of both interior and exterior spaces.; A BMP file is an uncompressed raster image comprised of a rectangular grid of pixels. It contains a file header (bitmap identifier, file size, width, height, color options, and bitmap data starting point) and bitmap pixels, each with a different color.
