Quick answer: To send a large RAF file, upload it to Share Large Video Files (up to 20 GB, no account) and share the download link: the file arrives unchanged. One 40 MP RAF photo, lossless compressed is about 50 MB, more than most email providers accept.
What is a RAF file?
RAF is Fujifilm's raw format, used by X-series cameras such as the X-T5 and X100VI and by the medium-format GFX range. Most X-series bodies use Fujifilm's X-Trans sensor, which some raw editors handle differently from standard sensors.
Fujifilm offers uncompressed, lossless compressed and (on newer models) compressed RAW. GFX medium-format files are especially big because the sensors go up to 100 MP.
Extensions: .raf.

How to send RAF files without changing them
- Open Share Large Video Files in any browser and choose Get a link (or Send by email).
- Drop RAF files on the upload box, or pick a whole folder. Up to 20 GB and 1000 files per transfer.

- Copy the link (or show the QR code) and send it by chat or email. The recipient downloads the original file, byte for byte.
Tips for sending RAF files
- If you used film simulations, send JPEGs too; raw editors do not always reproduce the in-camera look.
- Keep .XMP sidecars with the RAF files if you have edited them in Lightroom.
- For GFX shoots, split the delivery into several transfers so each stays under 20 GB.
- Keep the original file names so the recipient can match raws to JPEGs.

Frequently asked questions
Why does my RAF file look different from the camera JPEG?
The JPEG includes your film simulation and in-camera processing. Raw editors start from neutral sensor data, so apply a matching profile or send the JPEG as well.
How big is a Fujifilm GFX RAF file?
On a 100 MP GFX, about 200 MB uncompressed and roughly half that with lossless compression.
Can I open RAF on Windows without paid software?
Yes. Fujifilm X RAW Studio is free, although it needs the camera connected; darktable and RawTherapee are free alternatives.
