What's the difference between Personal and Studio?

Personal ($39) is for one person — unlimited use on one active device at a time. Activate on a new device and the old one signs out. Studio ($199) is for teams and commercial client work — unlimited team members, early access to new tools, and a commercial license.

Do I need an account?

No. Use any tool free up to 5 times per day on compute-heavier tools, and unlimited on lightweight ones. No card, no account, no signup required.

Where are my files processed?

Right on your device. Files never upload to any server. Everything runs in your browser — you can verify in DevTools → Network.

What happens if I use my Personal license on a second device?

The new device activates and the old device signs out. Your license key stays the same — you just move it between devices as needed. No limit on how often you switch.

Does this work on my phone?

Yes. Every tool works on iPhone, Android, tablet, and desktop.

What if I want a refund?

30-day money-back guarantee on both tiers. No questions asked. Email sales@cipherforces.com.

Will you add more tools?

Yes. New tools ship regularly. Your license includes every tool we ever release — Studio members get early access.

About Color by Numbers.

Turn Any Photo Into a Printable Color-by-Numbers Sheet

Upload a photo and CipherForces Color by Numbers quantizes the colors to a limited palette, outlines every region in black, numbers each region, and prints a color-key legend directly underneath the image — all on one sheet sized for Letter paper. Great for kids, relaxation, teaching, or community art.

Common Use Cases

Kids' crafts: Make a personalized color-by-numbers sheet from a family photo.
Adult coloring: Convert vacation shots or pets into meditative coloring sheets.
Classroom activities: Teachers generate custom worksheets for art lessons.
Gifts: Print a color-by-numbers portrait for friends and family.

Key Features

Adjustable palette: From 10 colors (simple) to 40 (detailed).
Outline thickness: Thicker outlines for young kids, thinner for adults.
Minimum region size: Avoid tiny specks no one can fill — hide regions below a size threshold.
Printable PNG: Single high-resolution PNG sized for Letter paper, with the numbered image on top and the color key laid out underneath.

Note: Output is a PNG image, not a multi-page PDF. The color key is printed directly below the numbered image on the same sheet. For pure line-art coloring pages (no numbers, no palette), use a different tool.

Privacy: Image processing is purely local. No photo is uploaded.
