Good to know
RW2 is the raw format Panasonic Lumix cameras write. Like most raw formats it is a TIFF-derived container holding the unprocessed readings of every sensor photosite behind a colour filter mosaic, plus the shot settings and a JPEG preview. A raw file is not yet a picture: it has to be developed by reconstructing full colour at each pixel and applying white balance and a tone curve, which is why an RW2 does not open in ordinary image viewers.
Because Panasonic stamps its own value in the place where a TIFF file declares itself. A normal TIFF starts with a byte-order mark followed by the number 42, and Panasonic writes a different number there, so any program that checks for the 42 before continuing rejects the file outright even though everything after that point is a well-formed TIFF directory. This tool does not check that number: it walks the directory structure and validates the offsets and the JPEG signature it finds, which is what actually proves the file is what it claims to be.
It is exactly as good as the JPEG the camera would have saved in JPEG mode, because that is what it is. What you give up is latitude: recovering blown highlights, lifting deep shadows or changing white balance needs the sensor data and a developer such as Silkypix, Lightroom or darktable. For sharing and printing, the embedded JPEG is the picture as the camera intended it.
No. The RW2 container is parsed by JavaScript in your browser tab and the extracted JPG is written straight to your disk. Nothing about your photos is transmitted or stored anywhere.
