ARW to RAF

Looking to convert ARW to RAF? Here's the honest answer — and what works instead.

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

Why ARW 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 ARW.

2

A ARW has already been processed

Your ARW 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:

Frequently asked questions

No. RAF stores the raw signal a Fujifilm sensor recorded at capture. A ARW is a finished image with that data already baked in and discarded — there's nothing for a converter to reconstruct.

RAW formats like RAF give maximum editing latitude — but only when they come straight from the camera. Converting a ARW to RAF would just wrap a finished image in a RAW container, with none of the benefits.

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 ARW into RAF or any real RAW.

ARW converts cleanly to PNG, JPG, TIFF and WEBP — free, no sign-up, no watermark.
