Convert cat to png

What is the difference between .cat and .png?

Description: The CAT file type, associated with Photomatix, is a proprietary file format used by Photomatix software, which is a popular tool for creating and editing high dynamic range (HDR) images. This file format is specifically designed to store data and settings used during the HDR photo editing process, such as tone mapping and exposure blending options. By saving a project as a CAT file, users can preserve their editing workflow, allowing for easy revisiting and adjustment of HDR images at any point in the future. This makes the CAT file format an essential asset for photographers and digital artists who frequently work with HDR imaging in Photomatix.; 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.
