PNG (Portable Network Graphics) is a raster image file format released in 1996 as a replacement for JPEG. That said, PNG uses lossless compression that gives it a small file size while still maintaining the original image quality. Today, PNG format is widely used to share image graphics over the internet and is supported by programs like Paintshop Pro, Adobe Photoshop, Microsoft Paint, Apple’s Preview, etc.
BMP, also called a bitmap image, is a raster image file format developed by Microsoft Corporation for its Windows operating system. Typically, BMP is used to save bitmap digital images in a display device and can save two-dimensional photos in monochrome and color. Although most BMP files have significant file sizes because of lack of data compression, they can be compressed losslessly via algorithms like ZIP.
