Convert Fujifilm RAF to JPG
X-Trans sensors need a demosaicing algorithm that understands their unusual filter layout.

RAF is Fujifilm's RAW format. What makes it distinctive is not the container but the sensor underneath most X-series bodies: X-Trans uses a 6×6 colour filter pattern instead of the 2×2 Bayer pattern nearly every other camera uses. Fuji designed it to suppress moiré without an optical low-pass filter, and it does — but it means the demosaicing step has to work differently.
This has a practical consequence people notice: X-Trans files rendered by converters that were tuned for Bayer sensors can show odd texture in fine detail, sometimes described as a smeared or "wormy" look in foliage. Different converters handle it with visibly different success, which is why Fuji shooters argue about RAW converters more than most.
Not every Fujifilm camera uses X-Trans. The GFX medium format line and several entry-level X models use conventional Bayer sensors, and their RAF files are ordinary in this respect.
Fuji's in-camera film simulations — Velvia, Classic Chrome, Acros — are rendering instructions, not pixel data. No third-party converter reproduces them, including this one. What you get here is a neutral rendering of the sensor data; if the film simulation look is what you are after, the camera's own JPEG or Fuji's software is the way to get it.
Your files never leave this device. The decoder runs as WebAssembly inside this page, so there is no upload step and no server that could retain a copy. With RAW this is not just a privacy point — it is why the tool is usable at all, since uploading a card full of 30 MB files over a home connection would take longer than the shoot did.
Common questions
- Will my Fujifilm film simulation be applied?
- No. Film simulations are a rendering recipe the camera applies when it makes a JPEG; they are not stored as pixel data in the RAF. No third-party converter can reproduce them. This tool gives you a neutral rendering to start from.
- Does it handle X-Trans sensors properly?
- It demosaics X-Trans files, yes. Be aware that X-Trans rendering quality varies noticeably between converters — this is a known area where dedicated Fuji-aware software such as Capture One or Fuji's own tools may resolve fine foliage detail differently.
- Are my RAF files uploaded to a server?
- No. Decoding and encoding both run in your browser via WebAssembly. Nothing is transmitted. You can verify it in the Network tab of your devtools during a batch, or by disconnecting from the internet once the page has loaded — the tool keeps working.
- How many files can I convert at once?
- There is no limit in the tool. RAW files are large, and each one is decoded to a full floating-point buffer, so memory is the real constraint. Batches of a few dozen are comfortable on a typical laptop; for a whole card, work through it in groups rather than dropping a thousand files at once.
This converter is part of a full editing pipeline — tone, colour, lens correction and batch export all run the same way, without uploading.
