Convert NRW to FLIF

The NRW file extension stands for Nikon Raw Image, a proprietary raw image format used by Nikon digital cameras, particularly the high-end COOLPIX models. NRW files store uncompressed, unprocessed image data, allowing for greater post-processing flexibility and higher image quality compared to compressed formats like JPEG. Introduced to support Windows Imaging Component (WIC) functions, NRW files enable photographers to adjust color, brightness, and other image attributes with precision. Compatible with various image editing software, including Nikon ViewNX2 and Adobe Photoshop, NRW files are essential for professional photography.

The Free Lossless Image Format (FLIF) is a lossless image compression format designed to outperform other formats like PNG, lossless WebP, and JPEG 2000 in terms of compression ratio. Introduced in 2015, FLIF uses MANIAC (Meta-Adaptive Near-zero Integer Arithmetic Coding) for efficient compression, making it suitable for various image types without quality loss. Despite its advantages, FLIF development ceased as it was superseded by JPEG XL.
