Pixel Art vs Voxel Art
ピクセルアート / ボクセルアート
Both sit in Digital Image Techniques, so the question is not what they belong to but how they behave. One is technique and the other style. They are reached for with some of the same intent, which is where they get confused.
Pixel Art

Treats the pixel as an honest unit, building clear form from limited resolution and palette.
Voxel Art
Voxel art divides three-dimensional space into equal volume elements and leaves those units visible as the smallest pieces of form and color, carrying pixel art's productive limits into volume.

|---|---|---|
| Era | 1970s– | 1990s– |
| Family | Digital Image Techniques | Digital Image Techniques |
| Kind | Technique | Style |
| Cues | Visible pixels / Limited palettes / Tiles / Sprites | Contours and surfaces exposing equal cubes / Curves translated into stepped volume / A small restricted palette applied face by face / Box-like scenes read in orthographic or weak perspective |
| Best used for | Icons and controls for small screens that stay clean when scaled up · Game characters and terrain that must read apart at tiny sizes | Making game worlds, maps and diagrams whose volume can be stacked, removed or exposed · Producing consistent miniature 3D icons and scenes from few colors and units |
| Type | Draw letters on the same grid, fixing cap height in pixels | Build lettering from the same cube grid and do not mix it with smooth conventional type. |
| Composition | Scale only by whole multiples and keep every element on grid | Fix an isometric or orthographic view and keep the main silhouette clear of background cubes. |
| Material | Limited palette, dark outlines, neighboring hues to soften the steps | Fix voxel size and palette first, leaving slopes and curves as stepped volumes rather than subdividing them away. |
| Caution | Downscaling a photograph skips the decision behind every single pixel, and the contours turn muddy the moment the image is enlarged. | Square-looking low polygons are not voxel art. Form must be constructed from occupied units of a regular three-dimensional grid. |
