XnView Software

To resize image we need to open it and press Shift + S. Then we can see dialog window where more options to do that, and also some options to “Resamle”, like Lanczos, Nearest Neighbour, Bilinear, Hermite etc. My question is what the reason between them?
P.S. is it possible to make multiple resize in the future, not just for one image?

In batch convert
