A hidden picture
that appears when brightened.

Your picture is written in shades only one to six steps apart, which your eye can't tell apart. Boost the brightness or contrast, or drop it into our reveal tool, and it jumps out.

How it works

  1. 1

    Drop the picture to hide

    Bold shapes and text work best.

  2. 2

    Pick the cover colour

    Almost black, almost white, or a tint.

  3. 3

    Download the PNG

    Send it as a file so the tiny differences survive.

Good to know

  • JPEG re-saves can blur shades this close; PNG keeps them.
  • Fewer shades hide better but need more brightening.

Questions

Is it free?

Yes. It runs in your browser, so your pictures are never uploaded.
