Below is an image that shows you where to find the interpolation drop down and what it will look like. Well, there are interpolation options like Cubic and Linear in the scaler tool, but they make the art overly-blurred. I'm trying to find one where it evens out the pixel sizing, but interpolates it juuuuust enough to make the pixels appear sharp, but still uniform, no matter how they're sized. · GIMP includes three interpolation algorithms in the “Quality” section of the Scale Image dialog: Linear, Cubic, and Sinc (Lanczos3).
Generally speaking, Sinc is regarded as the best, but it would not hurt to try Cubic if Sinc gives you artifacts. Unless the image is very small or incredibly detailed, cubic and bicubic interpolation helps keep edges smooth.
According to Wikipedia, it can sometimes increase perceived contrast or cause artifacts. Lanczos: This interpolation method is much like cubic except that instead of.

Bicubic interpolation. Better scaling methods include bicubic interpolation, Lanczos resampling and Mitchell-Netravali filters. This was a wonderful thing to learn, and a real feeling of accomplishment when the high-bit-depth options I wanted paid off.

There are following five types of interpolation options are available in GIMP: None; Linear; Cubic; NoHalo; LoHalo; Cubic: In this method, each pixel color is calculated as the average color of the eight closest pixels in the original image.
