ARW stands for Sony Alpha Raw - Sony Digital Camera Raw Image format. ARW file extension is used by three DSC series of Sony cameras, but the format mostly is associated with "alpha" DSLR series.
ARW format is based on widely accepted TIFF format and TIFF specifications, which means that contains raw, uncompressed image data as captured by camera's sensors, and can be adjusted before exporting to common used image formats as JPG, PNG, GIF and others.
Different models of Sony cameras may store RAW images using the same .arw extension, but their format can be different. That is because sensors that capture image data on different camera models are different and so the image data format can be different.
ARW file format is RAW format which means that contains minimally processed data from camera sensors, and as that is not viewable for most of image viewers. That also means that is not supported by internet browsers and as RAW format can't be viewed directly on the browser.
