So in other words the image, when used as a slide background, is not altered nor compressed in PowerPoint. You can conclude that the presentation’s size is 0.03 MB and the image is kept 1 on 1 in the presentation. To be exact: the image is 4.08 MB and when the presentation measures 4.11 MB. When you would use that compressed image of 4.2 MB as a slide background image (Format Background, Picture or texture Fill), and then save the presentation, you would see that the presentation’s file size is 4.2 MB. That is compression.įile Size Observations: Image as Slide Background So, instead of writing black pixel, black pixel, black pixel, … 1000 times, the compressed format will write: 1000 x black pixel. In stead of storing 1000 times the black color information, pixel by pixel, the compressed equivalent will store a repetition of 1000 times a black pixel. a black wall, then each pixel of that wall, has the same color. There is obviously repetitive information in a RAW image. My photo has a resolution of 5835 by 3890 pixels, so in total almost 24 millions pixels. By compressing the image, we are taking out that massive amount of information by using compression techniques. We can use this JPG image directly in PowerPoint here. Almost 7 times smaller than the original RAW photo. The compressed JPG equivalent of this same image still contains a dimension of 5835 by 3890 pixels, but the file size is 4.2 MB now. You need to convert the image to, for example, a compressed JPG image. But you cannot use RAW images in a PowerPoint directly. Each pixel of the RAW photo, contains the most information possible. Because the image is not compressed, it contains the maximum amount of information. A given RAW photo, taken by a SLR camera, might have a dimension of 5835 by 3890 pixels, and its file size is 27 MB. Let’s share some expert knowledge on PowerPoint and images.
