Creating custom connect-the-dots activities has never been easier. Whether you are designing children's activity books for Amazon KDP, preparing classroom worksheets, or building homeschool resources, this free dot-to-dot generator gives you full control over every aspect of your puzzle. Upload any reference image — a simple outline, a photograph, or hand-drawn artwork — and trace along the contours by clicking to place numbered dots.

The tool runs entirely in your browser. No account required, no data uploaded to any server, and no limits on the number of puzzles you can create. Each puzzle exports as a clean, print-ready PDF at high resolution, ready for commercial printing or home inkjet printers. The exported file contains only the numbered dots on a white background — no reference image, no connecting lines — so kids see only the puzzle, not the answer.

Teachers, parents, and self-publishers around the world use connect-the-dots activities in worksheets, activity books, party printables, and more. With this generator, you can create puzzles tailored to any age group or difficulty level by controlling how many dots you place and how far apart they are.

Frequently Asked Questions

How does the dot-to-dot generator work?

Upload a reference image (optional), then click anywhere on the canvas to place numbered dots in sequence. The dots form a path that, when connected, reveals the image. When you're done, export the puzzle as a PDF — the exported file shows only the dots and numbers on a clean white page.

Can I upload my own image as a reference?

Yes. You can drag and drop any image (PNG, JPG, SVG, WebP) onto the upload zone. The image appears as a faded background on the canvas so you can trace along its outline. Adjust the opacity slider to make the reference lighter or darker. The reference image is never included in the exported PDF.

How many dots can I place?

There is no hard limit. You can place as many dots as you need. For young children (ages 3-5), 10 to 20 dots works well. For older kids (6-10), 30 to 60 dots creates a more challenging puzzle. For adult activity books, you can go well beyond 100 dots for highly detailed images.

Is the exported PDF print-ready?

Yes. The PDF is generated at high resolution with precise dot placement mapped to the exact page dimensions (Letter or A4). The output is suitable for professional printing, Amazon KDP interiors, and home printers alike.

Can I use this for commercial projects (KDP books)?

Absolutely. The tool is free to use for personal and commercial purposes. You retain full rights to the puzzles you create. Many users create dot-to-dot activity books for Amazon KDP, Etsy printables, and classroom resource packs.
