Convert rlb to png

What is the difference between .rlb and .png?

Description: The RLB file format is associated with Wavefront, a type of advanced graphic software used primarily in the creation and rendering of 3D graphics and animations. Specifically, RLB files store raster image data generated by Wavefront applications. These files are used to store texture information, digital images, or bitmap graphics that can be mapped onto 3D models within the software. The format is designed for use within the Wavefront ecosystem for high-quality visual effects and animation projects.; 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.
