Tattoo stencil maker
Drop an image into the tattoo stencil maker, set the threshold and the line thickness, then print the result at true scale and measure it with a ruler.
Or drop a PNG, JPG or WebP here. The image is processed on your own device and never uploaded.
A stencil is the map the artist works from. It goes onto your skin in purple carbon and every line in it becomes a line in you, so it has to be one clean closed outline at the right size, with no grey and no colour. The tool here does that part, cutting an image down to black and white at a threshold you control.
Everything happens in your browser. The image never leaves your device, there is no upload and no account, and the tool is free. What it cannot do is turn a bad source image into a good stencil, which is most of what follows.
What a stencil has to be
The threshold slider is the whole trick. Every pixel darker than the cut becomes black and everything lighter becomes white. Line art with real black lines on white paper survives that cleanly. A pencil drawing needs the threshold pushed until the light strokes appear, and the dark ones thicken as a side effect, which is what the line thickness control is there to fix.
The four things that matter
- One line of even weight, closed wherever two lines meet, so the artist can see what connects to what.
- No grey and no gradients, since thermal transfer prints a single purple line and anything in between comes out solid or vanishes.
- No colour information, because colour decisions happen with ink and not with the stencil.
- A locked size, written on the sheet in centimeters, so nobody rescales it at the shop.
Why a photo makes a bad stencil
A photograph has no outlines in it. It has tonal edges, and a threshold turns those into islands of black that mean nothing on skin. Run a portrait through any stencil tool and the shadow under the nose becomes a solid shape while half the cheek disappears.
Line art is what works: a pen drawing scanned at 300 to 600 dpi in black ink on white paper, a digital drawing exported at the size you plan to get, or flash from an artist who sells it for that purpose. If a photo is all you have, get it redrawn as linework, or describe the subject in the generator, which returns designs with clean outlines and a stencil already separated out.
| Source image | What happens to it | Usable |
|---|---|---|
| Inked line art on white paper | Lines stay, the paper drops out | Yes, scan it at 300 to 600 dpi |
| A pencil sketch | Light strokes vanish until you push the cut | Yes, with the line thickness turned up |
| A digital drawing with flat black lines | Clean at almost any setting | Yes, export it at final size |
| A photo of a face or an animal | Shadows go solid, mid tones disappear | No, it has to be redrawn |
| A screenshot from social media | Compression noise turns into speckle | No, the edges break up |
| A shaded black and grey design | Grey goes either solid or white | Only the outline survives |
Printing at true scale
Printing is where most home stencils go wrong, and the fault is almost always a print dialog that quietly resized the page.
Printing without resizing
- Set the scale to 100 percent, or pick Actual size. Turn off Fit to page and Shrink oversized pages.
- Match the paper size in the dialog to the paper in the tray. An A4 layout printed on US Letter with fit enabled comes out about 6 percent small.
- Print a 10 cm reference line beside the design, then measure that line with a ruler before you measure anything else.
- Measure the design itself in centimeters and write the number on the sheet.
- If the reference line is short, fix the dialog and print again. Do not scale the design to compensate.
Getting it onto skin, and what your artist will do with it
Studio stencils are printed on thermal paper, four sheets stacked together: a white top sheet, a thin tissue layer, a purple carbon sheet and a backing. The tissue comes out, then the pack goes through a thermal printer or gets traced on top with a ballpoint, pressing carbon onto the back of the top sheet. Thermal printers start around $250, so most people print on plain paper and let the shop make the stencil from it.
Applying it has a sequence. The area is shaved and cleaned, a thin layer of stencil solution or antiperspirant stick goes on, the sheet is pressed flat for 20 to 30 seconds without sliding, peeled off in one direction, then left to dry for ten to fifteen minutes.
A stencil you bring is a starting point for a conversation. Artists redraw to fit the limb, change line weights for how the piece will heal, and move things once it is on the body, and many charge for that drawing time whether you brought something or not. Turn up with a true scale print and the size written on it, and you have done the part that genuinely helps. If the design itself is still open, generate it first: the generator returns four versions plus a print ready stencil at the size you set, free with an account.
Questions people ask
How do I make a tattoo stencil at home?
Start from line art. Cut the image to pure black and white with a threshold, set the line weight so nothing is thinner than about 1 mm at final size, print at 100 percent scale and measure the print with a ruler. Trace it onto thermal paper with a ballpoint if you have some, or hand the print to your artist.
Can a tattoo stencil generator work from a photo?
It will produce something, and it will not be usable. A photo has tonal edges instead of outlines, so the threshold turns shadows into solid blobs that mean nothing on skin. Photographs have to be redrawn as linework first, either by an artist or by generating a line design of the same subject.
What paper do I need for a tattoo stencil?
Thermal or hectograph stencil paper, which comes in four layer packs. You pull out the middle tissue sheet, then either run the pack through a thermal printer or trace the design on the top sheet with a ballpoint. Plain paper is fine for checking size and for handing to your artist.
How do I print a tattoo stencil at the right size?
Turn off every scaling option in the print dialog, set 100 percent or Actual size, and match the paper size to what is in the tray. Print a 10 cm line next to the design and measure it. If that line is not 10 cm, the dialog is scaling and the design is wrong by the same amount.
Will a tattoo artist use a stencil I bring?
Many will treat it as a reference and redraw it, some will transfer it close to as drawn, and a few will not work from outside artwork at all. Ask when you book. A clean print at true scale with the measurement written on it is welcome almost everywhere.
