X3F is Sigma's RAW format, used by their cameras built around the Foveon X3 sensor, a distinctive design that captures full RGB color information at each pixel location rather than relying on the Bayer color filter array most other cameras use. X3F files still require processing before they're viewable, and since they aren't supported by browsers, photo viewers, or social platforms, converting to JPG is necessary anytime an X3F photo needs to be shared or viewed outside specialized RAW software.
Converting X3F to JPG processes the Foveon sensor data and compresses the result into a small, universally compatible file, which is the standard step once a Sigma shoot has been edited and is ready to share, upload, or print.
