We can export a mind map as an image, using any of the following three graphic file formats—JPEG, PNG, and SVG. We are going to analyze the options, although they are very simple. If the mind map has bitmaps, we can export the mind map as PNG (short for Portable Network Graphics). It is a file format that provides advanced graphic features and lossless compression. It is advisable to use this type of file format while working with bitmaps when we don't want to lose image quality while rendering the mind map to the final bitmap. In case we want to export the mind map in the file form with the smallest possible size, we can use the JPEG (short for Joint Photographic Experts Group) file format, which uses lossy compression. Pixels with different colors add noise to the image, and delete color information and replace it with pixels of approximated values. If the mind map has many photographs, the best choice for the smallest file size that will lose some image quality is JPEG. JPEG is a compressed graphic file that is used... Source.
