An ARW file is a raw graphic image taken from a Sony digital optical camera (Sony Digital Camera Raw Image). In essence, an ARW is a monochrome black-and-white digital photo file based on the TIFF format. The ARW extension is specifically designed to record bitmap graphic images with little or no additional processing from the high-sensitivity sensor of a Sony camera. Convert it for further work.
The PNG format was created to both enhance and replace the GIF format with a graphic format that does not require a license to use. Unlike GIF, PNG has alpha channel support and the ability to store an unlimited number of colors. PNG compresses data without losses, making it very useful for storing intermediate versions of image processing. Portable Network Graphics is a convenient format to place the file in an electronic document if it does not need to be printed later. PNG is completely unsuitable for printing, hence you have to convert it to print.
