Pixelation for Privacy and Art

Pixelation reduces image resolution in blocks, creating the classic mosaic effect. It serves two main purposes: privacy protection (blurring faces, license plates, or sensitive content) and artistic effect (creating retro 8-bit or Minecraft-style aesthetics).

Our pixelation tool gives you adjustable block sizes. Small blocks (2-5px) create subtle pixelation suitable for artistic effects. Large blocks (10-20px) provide strong anonymization that makes details unrecognizable while preserving the overall shape and color.

  • Use 4-8px blocks for face blurring in photos
  • Small blocks (2-3px) create interesting artistic pixel effects
  • Large blocks (15-20px) provide strong privacy protection
  • Pixelate BEFORE resizing if you need to maintain block visibility at different sizes
