Convert JPEG to RAF

Looking to turn a JPEG into a RAF file? Here's the honest answer — and what actually works instead.

You can't convert JPEG to RAF. RAF is a camera's own RAW format — it only ever comes out of the camera.

Why JPEG to RAF isn't possible

1

RAF is Fujifilm's in-camera RAW

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 JPEG.

2

A JPEG has already been processed

Your JPEG 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.

3

It is locked to one camera maker

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.

The RAW formats — and where they come from

Every real RAW file is one of these camera-maker-specific formats, written by the camera itself:

What is a JPEG file?

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.

Frequently asked questions

Can any tool convert JPEG to RAF?
No. RAF stores the raw signal a Fujifilm sensor recorded at capture. A JPEG is a finished image with that data already baked in and discarded — there's nothing for a converter to reconstruct.
Why would I want RAF anyway?
RAW formats like RAF give maximum editing latitude — but only when they come straight from the camera. Converting a JPEG to RAF would just wrap a finished image in a RAW container, with none of the benefits.
Is DNG different?
DNG is an open RAW container. You can convert a camera's own RAW (including RAF) into DNG, but you still can't turn a regular JPEG into RAF or any real RAW.
What can I convert my JPEG to instead?
JPEG converts cleanly to PNG, JPG, TIFF and WEBP — free, no sign-up, no watermark.
