2. Choose a style preset or adjust the controls manually
3. Click "Generate stencil" to process
4. Fine-tune until the result looks right
5. Download as PNG and print on hectographic paper

Tips for best results

• Use photos with good lighting and clear contrast
• Simple compositions work better than complex scenes
• Start with "Fine lines" preset and adjust from there
• Increase "Edge sensitivity" to capture more detail
• Use "Bold lines" preset for larger tattoo pieces
• Portrait photos work best when the background is plain

FAQ

What is a hectographic printer?

A hectographic (or thermal) printer is used by tattoo artists to transfer a stencil design onto skin before tattooing. The stencil paper requires a high-contrast black-and-white image with clear linework.

Is my photo safe?

Yes. All processing happens locally in your browser using the Canvas API. Your photos never leave your device.

Can I use this for any tattoo style?

This tool works best for traditional, neo-traditional, linework, and blackwork styles. For watercolor or hyper-realism styles, the result may need additional manual refinement.
