ARW
Sony RAW Image (ARW)
ARW is a proprietary raw image file format used by Sony digital cameras, storing uncompressed or lossless compressed sensor data.
What is Sony RAW Image (ARW)?
The ARW format stands for Sony Alpha Raw. Developed by Sony, it contains raw pixel data captured by the camera's image sensor along with metadata like white balance, exposure, and camera settings. Because it lacks compression artifacts and retains maximum dynamic range, photographers prefer ARW for professional editing and post-processing. To share these images easily, you can use ConvertX tools like arw-to-jpg, arw-to-tiff, or arw-to-png.
