PNG’s DEFLATE algorithm achieves better compression than GIF’s LZW algorithm.PNG’s ancillary data sections support compression allowing their overall size to be reduced.The size of PNG palette entries can be smaller than the corresponding GIF palette entries on images with less than 256 colors.Let’s name a few to get a better picture: The PNG format was defined 10 years after the GIF format, allowing PNG images address some of the flaws that GIF was facing. PNG images are also a lossless image format that very closely mirrors GIF images. Pay close attention, because this is where the PNG format sweeps in and takes the win. GIF comments, metadata, and Application Extension sections don’t contribute to the rendering of the graphic data. Being an 8 bit-depth image format it would have disappeared from the web after the introduction of the JPEG and PNG file formats, but GIF is still a favored web file format thanks to its frame animation feature. GIF is the standard format for compressing images with large areas of solid colors and crisp details like those in line art, logos, or type. GIF is a lossless image format, which features the ability contain multiple graphic images inside of a single file.

Let’s start off by exploring the GIF image format and how to optimize it. Understanding images and how to optimize them are skills for anybody dealing with frontend performance. Despite the fact that video is taking over the web traffic, images make the majority of all web content. There is a number of ways to do that, such as using HTTP compression to reduce the size of the data that needs to be sent to the client. A great way to lose the wait is to trim the fat, as in the weight of your page content. Having a smooth, fast loading website is key to optimal user experience.
