How to make a stencil from a photo
Add your photo
Drop a picture, paste one, or pick a file. Clear subjects with strong contrast work best: a face in side light, a logo, a silhouette.
Tune the look
Drag Detail until the shapes you need are black and the noise is gone. Raise Remove specks to clean up. Switch between Cut stencil and Line art any time.
Download and use it
Save a PNG, an SVG for a cutting machine, or a PDF to print. Print at the size you need and always test on scrap first.
What this stencil maker does
StencilBench is a free online stencil maker. You give it a picture, and it returns a two-tone version where every pixel is either cut away or left as sheet. The conversion runs in your browser, so there is no upload, no account and no waiting in a queue.
It handles the two jobs people usually mean by “image to stencil”. The first is a solid cut stencil: shapes you can cut from card, acetate or vinyl and spray through. The second is a line drawing you can trace by hand or print onto transfer paper. You can switch between them on the same photo and compare.
Bridges decide whether a stencil survives cutting. Many photos produce shapes that would fall out once cut, such as the inside of an O, the white of an eye or the middle of a ring. StencilBench finds those islands and adds thin bridges that hold them in place, so the stencil survives being cut.
Settings explained
Cut stencil or line art
Cut stencil turns your photo into solid black and white shapes. Black is what gets cut out, so paint or ink goes through it. White is the sheet that stays. Line art draws only the edges as black lines on white, which suits tracing and transfer paper.
Detail
In cut stencil mode, Detail sets how dark a pixel must be to turn black. In line art mode it sets how faint an edge can be and still get a line. If your stencil is a solid black blob, lower it. If shapes are missing, raise it.
Smoothing and Remove specks
Smoothing blurs the photo slightly first, which removes skin texture and grain. Remove specks deletes black bits below a size you choose. In cut stencil mode it also fills tiny white holes, since those would be too small to hold together as paper.
Bridges
A bridge is a thin strip of sheet that ties an island to the rest. Think of the middle of the letter O or the pupil of an eye. Without a bridge, that piece falls out when you cut. StencilBench finds each island and joins it to the main sheet along the shortest path. Widen the bridge for flimsy paper, narrow it for fine detail.
Photos that work well
High contrast
Pick a photo with a clear difference between subject and background. A face lit from one side gives far cleaner shapes than a flat, even snapshot.
Simple background
Busy backgrounds turn into noise. Crop tightly first, or use a picture where the subject stands against a plain wall or sky.
Large enough
Very small or heavily compressed pictures give blocky edges. StencilBench scales large pictures down to 1600 pixels on the long side to keep things fast.

Frequently asked questions
Is this image to stencil converter really free?
Yes. The converter, bridges and the PNG, SVG and PDF downloads are free, with no watermark and no sign-up. A Pro tier for multi-layer files and poster printing is only planned and not for sale.
Do you upload my photo?
No. The picture is read and converted inside your browser tab. It is not sent to our servers and it is gone when you close the page.
What file should I download for a cutting machine?
Use the SVG. It traces the black areas as vector shapes that most cutting software can open. Check the preview in your software, and make sure bridges are on so islands stay attached.
How do I print a stencil at a bigger size?
The free PDF fits one page, Letter or A4. For a larger stencil, download the SVG and scale it in a vector or print program, or wait for the planned tiled PDF.
Why does my stencil look like a black blob?
The Detail setting is too high for that photo, or the picture has little contrast. Lower Detail, raise Smoothing, or try a different photo with brighter highlights.
Can I use stencils I make from any photo?
Only use pictures you have the right to use. The tool does not check ownership. You are responsible for the image and for how you use the stencil.
