CR3 is Canon's in-camera RAW
CR3 is the raw sensor data a Canon 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 CR3 from a finished RAF.
Looking to convert RAF to CR3? Here's the honest answer — and what works instead.
Turn your file into a share-worthy AI Effect — one tap, no prompts.
RAF is Fujifilm’s raw photo format, capturing full sensor data from X-series and GFX cameras.
RAF opens in Lightroom, Capture One and Fujifilm software.
CR3 is Canon’s newer, more efficient raw format used by recent EOS cameras — smaller than CR2 with the same flexibility.
CR3 opens in recent Lightroom, Photoshop, Canon DPP and modern raw editors.
No. CR3 stores the raw signal a Canon sensor recorded at capture. A RAF is a finished image with that data already baked in and discarded — there's nothing for a converter to reconstruct.
RAW formats like CR3 give maximum editing latitude — but only when they come straight from the camera. Converting a RAF to CR3 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 CR3) into DNG, but you still can't turn a regular RAF into CR3 or any real RAW.
RAF converts cleanly to PNG, JPG, TIFF and WEBP — free, no sign-up, no watermark.
