Using PNG to Base64 conversion can make it possible to embed an image directly into a document or application without referencing a separate image file. This can be convenient for small graphics, icons, and interface elements. It may simplify transferring image data through systems that work with text rather than binary files. However, Base64 is not an image compression method and usually makes the encoded data larger. For larger images, storing and serving the original PNG or an optimized image file may be more efficient.
