Convert crg to png

What is the difference between .crg and .png?

Description: The CRG file type is predominantly associated with Calamus, a sophisticated desktop publishing software targeted mainly at professional users. Developed initially for the Atari ST in the late 1980s, Calamus offers powerful tools for layout, text handling, and graphic design. CRG files specifically contain raster graphic data used and generated within the Calamus environment. These files enable users to manage and incorporate detailed graphic elements into their publishing projects, ensuring high-quality outputs for print and digital media.; A PNG file is an image file stored in the Portable Network Graphic (PNG) format. It contains a bitmap of indexed colors and uses lossless compression, similar to a .GIF file but without copyright limitations. PNG files are commonly used to store graphics for web images.
