![]() On the flip side, saving photography in PNG format produces larger files. The fewer individual colors an artwork uses, the higher the compression rate which can be achieved. The lossless PNG compression works by mapping pixels to a simple palette. PNG is the format of choice for screenshots, diagrams, logos, icons, and other graphical elements. It lends itself to complicated artworks and can maintain sharp contrast and lines without producing artifacts. PNG uses lossless compression and supports transparency. ![]() It was developed specifically for screen design and to replace GIF images with an open format with a larger possible palette. The Portable Network Graphics format or PNG for short produces raster images. JPEG compression often achieves a file size reduction by a factor of 10 without visible artifacts. For photography, a lot of the discarded data is not visible to the human eye (similarly to how audio formats discard data the human ear cannot distinguish). JPEG codifies red, green, and blue in blocks of 8x8 pixels. The JPEG compression works by discarding fine details, controlled by a quality factor, less quality, and less detail. Graphics, drawings, logos, screenshots, or text-heavy images which require sharp lines and definition are less suited for the file format. The sliding scale compression method can decrease file size considerably, but high compression rates result in increased artifacts, pixelation, and blur. Thanks to compression, faster load times and page rendering are possible with JPEG images. Web designers use JPEG for images with complex colors and shadings like paintings, photographs, and 3-D objects like flowers. This raster image format features lossy compression, which works quite well for photography. The name of this image format comes from the Photographic Experts Group, the technical team that developed it. Browser compatibility: Chrome, Edge, Firefox, Internet Explorer, Opera, Safari
