Looking to turn a JPG into a RAF file? Here's the honest answer — and what actually works instead.
You can't convert JPG to RAF. RAF is a camera's own RAW format — it only ever comes out of the camera.
RAF is the raw sensor data a Fujifilm camera writes at the moment of capture. It's produced by the camera's own hardware and firmware — software can read it, but nothing can manufacture a genuine RAF from a finished JPG.
Your JPG is a developed, final image. The extra sensor information a RAF carries — wider dynamic range, full color depth, untouched highlights — was discarded when the photo was first saved, and can't be put back.
RAF is proprietary to Fujifilm. Even other RAW formats (NEF, ARW, RAF…) aren't interchangeable with it — there is no universal "save as RAW" that produces a real RAF.
Every real RAW file is one of these camera-maker-specific formats, written by the camera itself:
JPG (JPEG) is a lossy raster format that compresses photographs into small files by discarding detail the eye barely notices — the most widely used photo format on the web and in cameras.
