Very low quality image format that allows you to store 8 bits per pixel for a total of 256 colors per image compared to 16 million JPEGs that reach the limits of what the human eye can see. In conclusion, the PNG does not present a risk of blurry images over time. I use PNG every time I present a logo in SlideMaster, work with the icon (unless you can use them in SVG or EPS, of course – see the definitive guide for the use of icons in PowerPoint), or images that should have a transparent background. Therefore, a PNG file compresses the image without losing the details of the original, which may not be displayed on the screen, but which can certainly be recovered by graphically editing the file.įor presentations, the most interesting feature of PNG is that it supports the transparent background layer, so you can get photos with transparent background thanks to this format, which I know from now on that you will adopt as the only format of your presentations. This image format is based on the LSW compression algorithm which, unlike JPEG compression, works without losing the initial information. In presentations, JPEG is good for photographs, but it is not good for graphics (lines, typography, drawings, etc…) because it tends to granulate the edges.įinally, JPEG is an image that lives on a level, so it will always have a white background that could create the problems that are seen above when we talk about transparent and non-transparent images.

In summary, the JPEG compression algorithm is based on the fusion of pixels that resemble each other.įor this reason, it is a file that significantly reduces the quality of the image with the advantage of weight and, therefore, can’t be used to store images because, once compressed, it can’t go back. It has a compression algorithm that reduces the size of an image, on average, 1/10 of the original size. One of the Image formats commonly used, widely used in the world of photography.
