Tattoo Stencil Maker

Turn a photo into a tattoo stencil

A tattoo stencil is the black outline you transfer onto skin before tattooing. This tool takes any photo, drawing, or reference image and extracts its edges into clean black line-art you can print and trace. It runs an edge-detection pass entirely in your browser — move the sliders and the stencil updates live, so you can dial in exactly how much detail you want.

Unlike most "photo to stencil" sites, your image is never uploaded — the whole conversion happens on your device, which matters when you're working with a client's personal photo or your own custom art.

Getting a clean stencil

• Start with contrast. Bold images with clear outlines trace far better than soft, busy photos.
• Line detail controls how sensitive the edge detection is — lower picks up fine detail, higher keeps only the strong outlines.
• Smoothing removes speckle from noisy photos; thickness fattens the lines so they survive printing and transfer.
• Print at 100% scale and apply with thermal/transfer paper.

FAQ

Is my image uploaded?

No. The conversion runs in your browser on a <canvas>. Open DevTools → Network and watch: nothing is sent anywhere.

What image works best?

High-contrast images with clear outlines — logos, bold drawings, well-lit subjects. Very soft or busy photos produce messy lines; raise "line detail" to simplify.

Can I print it to trace?

Yes — download the PNG and print at 100% scale, then transfer with thermal/transfer paper. Flip/invert if your method needs it.

Is it free?

Yes — free, no account.

For reference/design use. Always tattoo safely and hygienically; this tool creates artwork only.
