Convert RAF to FLIF

The RAF file extension stands for Fujifilm Raw Image File, a format used by Fujifilm digital cameras to store uncompressed image data directly from the camera's sensor. Introduced to preserve maximum image quality, RAF files contain minimally processed data, allowing for extensive post-processing flexibility. This format, based on the TIFF/EP standard, includes metadata such as camera settings and format version. RAF files are primarily utilized by professional photographers and enthusiasts for high-quality image editing and archiving.

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 Despite its advantages, FLIF development ceased as it was superseded by JPEG XL.
