My numbered grid

Waiting for a source image

How do I use this tool?

  1. 1.Choose your source

    Upload a photo with strong color separation and a single obvious subject.

  2. 2.Adjust and compare

    Try eight sampled colors and large cells, then refine only if important shapes are missing.

  3. 3.Download your result

    Save the PNG and prepare a manual color guide using the original photograph.

Before I download

Can it make a color-by-number puzzle with equations?

No. The numbers represent photo color groups, not arithmetic answers. Add educational tasks and an answer key separately if you want a teaching worksheet.

Can I choose exact pencil colors?

The palette is sampled from the photo and has no pencil-brand matching. Choose your own materials and use the original image as a guide.

Reduce the number of decisions

A small color count can make a complicated photograph easier to discuss or recreate as an exercise. Start with a bold subject such as fruit, a toy, or a flower. If different important areas merge into one group, add a few colors before making every cell smaller.

Understand the numbered-cell format

The conversion divides the picture into regular squares and groups sampled colors under numbers. It does not trace the exact contour of each object. The sheet contains faint color hints, but no independent palette key. Choose your materials with the original photo beside you, and record your own number-to-color choices if needed.

Save a reference you can read

The output is a PNG capped at 960 pixels on the longest edge. Small cells can make labels crowded, especially on a reduced print. Increase cell size and test again when readability matters more than fine detail.
