You can save the slides as images in PNG, TIFF or JPG. In the top menu select “File” > “Export to” > “Images…” Select the required format in a pop-up window and specify the range of slides that you want to save as images. If you want to save all the slides, check the point “ALL”. Press “Next…”.
In the opened window select the folder where you want to save the images. Set the default name for the slide. During the export, KeyNote will automatically add the sequence number to this name.
