Image Pixelator

Key features

• Block size slider from 2 to 64 px controls how coarse the mosaic is.
• Optional color quantization posterizes each channel to 2–16 levels for a limited-palette, 8-bit feel.
• A downscale-then-nearest-neighbor-upscale pipeline keeps the blocks razor sharp.
• Output keeps the original pixel dimensions — the look changes, the size does not.
• Live stats show blocks across and down, and the preview renders with pixelated rendering.

How it works

1. 1

   Drop In Your Image

   Any photo or graphic works as the source.

2. 2

   Drag The Block Size

   Small values give a subtle mosaic; large ones go full retro.

3. 3

   Optionally Quantize

   Flip the switch and pick levels per channel to flatten the palette further.

4. 4

   Save The Pixelated PNG

   Exported at full resolution with hard-edged blocks.

Tips for better results

• 💡8–16px blocks are a good retro range for typical photos.
• 💡Quantization at 3–5 levels per channel delivers the strongest old-school game look.
• 💡Blocks also obscure detail — handy for censoring faces or license plates before sharing.
