Works
Viewing, inspecting and verifying. You get the image (or the embedded full-size preview, for camera RAW) rendered on screen. File details, exact byte size and the detected signature are always shown.
How to open a .raf file
The short version: RAF is a Fujifilm RAW Image from Fujifilm. The longer version — including the quirk that trips most people up — is below, along with a viewer that runs entirely on your own device.
What is a .raf file?
Fujifilm RAW Image is an image format developed by Fujifilm, first appearing in 2000. It is normally produced by Fujifilm X and GFX cameras.
X-Trans sensors use a 6x6 colour filter array instead of the standard Bayer 2x2. Converters that assume Bayer produce smeared, worm-like detail, which is why RAF support varies so much between tools.

Open a .raf file in your browser
OpenAnyFile routes .raf to its TIFF/RAW decoder, which decodes the image (or the embedded full-size preview, for camera RAW) rendered on screen.
- Open the OpenAnyFile opener in this browser — nothing to download or sign up for.
- Drag your .raf file onto the drop zone, click to browse for it, or paste it with Ctrl+V.
- The extension is detected and the file is handed to the TIFF/RAW decoder.
- Your RAF opens on its own viewer page: the image (or the embedded full-size preview, for camera RAW) rendered on screen.
- Use fullscreen for a closer look, or download the file back out unchanged. No account, no upload, no watermark, no file-size gate.
What you can and cannot do with it here
Does not work
Editing and re-saving. OpenAnyFile is a reader, not an editor — for changes you still need special software or an equivalent.
Is it safe to open a {E} file on a website?
It depends entirely on whether the website uploads it, and almost all of them do. That is a real problem when the images file in question is a contract, a client deliverable or something under NDA. OpenAnyFile removes the question: the decoding happens inside your browser tab, so there is no transfer, no queue, no temporary storage and no retention window to read about in a privacy policy.
Frequently asked questions about RAF files
Can I open a .raf file without installing special software?
Yes. OpenAnyFile's TIFF/RAW decoder runs in your browser, so you can read a RAF file with nothing installed. You get the image (or the embedded full-size preview, for camera RAW) rendered on screen. For full editing you still need the original application — this is a viewer, not an editor.
How can I check a file really is a RAF file?
Look at the first bytes rather than the extension. A genuine RAF begins with 46 55 4A 49 46 49 4C 4D (FUJIFILM). Opening the file in OpenAnyFile shows that signature in the file-details panel, so a file renamed to .raf by mistake is easy to spot.
Is it safe to open a RAF file online?
With OpenAnyFile, yes, because nothing is uploaded. The file is read locally through your browser's File API and never leaves your device, so there is no server copy to leak, log or retain. That matters most for the kind of file people are least willing to hand to a random converter site.
What is a .raf file, exactly?
Fujifilm RAW Image — an image/x-fuji-raf format created by Fujifilm since 2000. X-Trans sensors use a 6x6 colour filter array instead of the standard Bayer 2x2. Converters that assume Bayer produce smeared, worm-like detail, which is why RAF support varies so much between tools.
Does the same viewer handle formats related to RAF?
Yes — the same engine also opens .arw, .cr2, .dng, so you can compare related files without switching tools.
