Convert CR2 to BMP — Free Online Converter

Canon CR2 files contain 14-bit lossless JPEG-compressed RAW data from Canon DSLRs like the 5D Mark IV, 7D Mark II, and 80D. Converting these files to BMP produces an uncompressed bitmap image where every pixel of the demosaiced sensor output is stored without any compression algorithm. BMP's simplicity makes it readable by virtually any application that can display images, from basic Windows Paint to sophisticated scientific analysis tools.

This conversion is typically needed when interfacing Canon DSLR photography with legacy industrial systems, scientific instruments, or automated quality control pipelines that require uncompressed BMP input. The 14-bit Canon sensor data is demosaiced, color-corrected using the camera's embedded DIGIC processing parameters, and written as a 24-bit RGB bitmap.

BMP remains a requirement for certain specialized systems that predate modern image codec support. Machine vision cameras in manufacturing lines, medical imaging viewers in clinics running older software, and forensic photography documentation systems sometimes mandate BMP as their input format. Canon DSLRs are widely used in forensic and medical photography, making this conversion practically relevant.

The absolute simplicity of BMP — a header followed by uncompressed pixel data in rows — also makes it useful for software development and testing. When developing image processing algorithms, BMP provides raw pixel data without any decoder dependencies. Researchers working with Canon DSLR captures in computer vision projects sometimes prefer BMP input to eliminate any variable introduced by decompression algorithms.
