Convert RW2 to TIFF

The RW2 file extension is the successor to the RAW format, used exclusively for raw images produced by Panasonic Lumix digital cameras. It stores unprocessed data from the image sensor along with a unique header containing metadata such as lens information, shutter speed, ISO settings, and color profile tags. The format allows for non-destructive editing by saving parameter adjustments as sidecar files or database entries rather than altering the original pixel data. It typically employs a proprietary lossless compression algorithm.

RW2 files are supported by professional post-production software including Adobe Photoshop (Camera Raw plugin), Adobe Lightroom, and DxO PhotoLab. Panasonic bundles the SILKYPIX Developer Studio software with their cameras for native decoding. Windows 10 and 11 users can view these files in the Photos app after installing the Raw Image Extension. macOS users can preview and edit RW2 files natively through the Preview app and Photos app, leveraging Apple's system-level raw engine.

The Tagged Image File Format (TIFF) is a container format for storing raster graphics images, originally created by Aldus Corporation in 1986 and currently controlled by Adobe Systems. Ideally suited for photography and desktop publishing, TIFF supports multiple color spaces (CMYK, RGB, Lab), various compression schemes (lossless LZW, Deflate, or lossy JPEG), and data tags that define image geometry. It conforms to the TIFF 6.0 specification and can accommodate multi-page documents and extensive metadata standards like Exif, IPTC, and XMP within its header structure.

Due to its status as a standard industry format for high-quality imaging, TIFF files possess robust native support across major operating systems, including Microsoft Windows Photos and macOS Preview. For advanced editing and layer manipulation, professional raster graphics editors such as Adobe Photoshop, GIMP, and CorelDRAW are required. Specialized viewing software like IrfanView or XnView can also render multi-page TIFFs that standard system viewers may display incorrectly.
