What is PNG?
Lossless raster images with transparency. A good fit for screenshots, diagrams, and graphics.
Technical details
PNG uses a signature followed by typed chunks such as IHDR, IDAT, and IEND; IDAT carries DEFLATE-compressed filtered image data. [1]
Background and compatibility
PNG is a lossless image format, and its defined color types support transparency through alpha samples or the tRNS chunk. [1]
