BMP is a standard image file format primarily used in Microsoft Windows. Its main characteristic is that it typically stores pixel data uncompressed, resulting in very large file sizes but offering perfect image quality. Although it supports some basic compression, BMP lacks the efficiency and features (like transparency) of modern formats, making its use mostly limited to simple, high-fidelity internal application images.

PNG

PNG was developed as an improved, non-patented replacement for GIF.supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images,and full-color non-palette-based RGB or RGBA images.A PNG file contains a single image in an extensible structure of chunks, encoding the basic pixels and other information.
