Convert PNG to EXR

Understanding png and exr file formats

PNG (Portable Network Graphics) is a popular raster image format known for its lossless compression and support for transparency. It is widely used for web graphics, icons, and images requiring high quality and transparency.

EXR (OpenEXR) is a high dynamic range (HDR) image file format developed by Industrial Light & Magic. It is commonly used in visual effects, animation, and professional photography due to its ability to store a wide range of color and brightness information, as well as support for multiple channels and deep data.
