RAF Image to FAX conversion is the process of transforming Fujifilm RAF raw image files into the FAX (fax image/document) format, typically a monochrome or bi-level image optimized for sending over fax systems. This conversion extracts the raw sensor data from the RAF file, applies demosaicing, tone mapping, and downsampling, then encodes the result into a fax-compatible raster (usually TIFF G3/G4 or a .fax container) suitable for transmission or archival.

RAF files typically use the MIME type image/x-raf and contain raw image data from Fujifilm cameras. FAX files use the MIME type image/fax and are commonly compressed using Modified Huffman or Modified READ codecs for transmission via fax machines. RAF is primarily for photography workflows; FAX is optimized for fax communications.
The FAX (.FAX) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like RAF Image.
While specific technical details aren't available here, FAX files generally serve the purpose of storing image effectively within their domain.

RAF Image files contain raw, uncompressed data from digital cameras, offering high-quality images ideal for editing. FAX files are monochrome, compressed images specifically designed for fax transmission and storage. While RAF files are rich in image data, FAX files prioritize efficient transmission over image fidelity.
Keep individual RAF files under 10–50 MB for faster processing; large RAFs (100+ MB) will increase conversion time and memory use.
Preserve quality by rendering from the RAW data with proper white balance and exposure before converting to the 1-bit/greyscale fax format; use a high-resolution grayscale render if you plan to threshold manually.
For batch conversion, process files with consistent exposure and orientation settings and use automated presets to apply uniform thresholding and resizing to produce consistent fax pages.
Limitations: FAX is a low-bit-depth format intended for text and simple graphics—photographic detail will be heavily reduced and color information lost during conversion.
