The Complete Guide to Image Pixelation, Retro 8-Bit Aesthetics & Mosaic Privacy Censors

From the nostalgic charm of 1980s Nintendo and Sega arcade gaming to modern television broadcast news privacy redaction, image pixelation serves as both an iconic artistic style and an essential privacy tool.

What is Pixelation and How Does it Work?

Pixelation (also known as a mosaic filter) is a graphical downscaling and nearest-neighbor resampling technique. The algorithm divides your high-definition image into a grid of discrete square blocks (e.g. 16×16 pixels). It averages all the individual RGB color values inside each block and fills the entire tile with that single color.
