From IndieWeb

pixel art are images that are intentionally low-resolution, sometimes used as icons on indieweb sites. These pixel art images should be scaled up using nearest neighbor scaling.

Rendering Pixel Art

Use the image-rendering: pixelated CSS property so that pixel art scales as intended.

.u-pixel-art {
    image-rendering: pixelated;  /* Chrome */

    /* Firefox */
    image-rendering: crisp-edges;
    image-rendering: -moz-crisp-edges;

    image-rendering: -webkit-optimize-contrast;  /* Safari */

See lospec's guide on all the pixel art scaling options.
