Convert CRW to J2C

The CRW file extension stands for Canon Raw CIFF Image Format, a raw image file format used by Canon digital cameras. Developed to store uncompressed and unprocessed images, CRW files offer high-quality image data that can be edited with Canon's software or third-party editors like Adobe Photoshop. Introduced by Canon, this format has been largely superseded by newer formats like CR2 and CR3 but remains significant in the history of digital photography for its role in preserving image integrity.

The J2C file extension stands for JPEG 2000 Code Stream, a format defined in Part 1 of the JPEG 2000 standard. Developed by the Joint Photographic Experts Group (JPEG) from 1997 to 2000, J2C files utilize wavelet-based compression, supporting both lossy and lossless compression. This format is primarily used for high-quality image storage and transmission, offering superior compression efficiency and flexibility compared to the original JPEG standard. J2C files are often embedded within other file formats like JP2 for enhanced metadata support.
