What is an ARW file?
The ARW (Sony Alpha Raw) format is a proprietary raw image container generated by Sony Alpha, Cyber-shot, and NEX series digital cameras. It adheres to the TIFF (Tag Image File Format) specification, storing unprocessed photodiode data from the image sensor in either uncompressed, lossless compressed, or lossy compressed (11-bit + 7-bit delta) variations. The file encapsulates extensive EXIF metadata, maker notes, and a JPEG preview, requiring specific demosaicing algorithms to interpret the Bayer pattern data for display.
How to open an ARW file
Opening ARW files requires software capable of decoding Sony's proprietary Bayer interpretation. Sony provides the free Imaging Edge Desktop software for native handling. Industry-standard post-production tools such as Adobe Lightroom, Capture One, and DxO PhotoLab offer full support. On Windows, the Microsoft Raw Image Extension allows native viewing in the Photos app, while macOS Preview supports most ARW iterations natively via Apple's Core Image RAW engine.

What is a TIFF file?
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.
How to open a TIFF file
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.
