How Bicubic Interpolation Keeps Resized JPEGs Sharp

When resizing JPG images, nearest-neighbor scaling produces jagged stair-stepping edges. PixEnhance employs 16-point bicubic interpolation to sample adjacent pixel color coordinates smoothly.

This produces natural color transitions, sharp text lines, and crisp photographic clarity whether you scale down a 48MP smartphone shot or scale up a graphic.
