Most reference photos live on your phone as JPGs. Drop one in and HectoInk pulls clean stencil lines out of it, even from compressed phone photos. Adjust detail and line weight, set the exact width, and download files that print at true size on standard thermal stencil paper.
Free preview. No account. Your image is converted, not stored.
Starting presets, not lab calibrations: they nudge line density and weight for common printer and paper combos. We tune them with working artists' feedback.
Every pack: true-size tiled print PDF, exact-size PNG at 300 DPI, SVG, and a run sheet with print instructions.
Heavy compression can soften edges in the photo, but the line extraction works from the shapes in the image, so a normal phone JPG converts fine. If the lines look rough, nudge the detail setting down and the stencil will smooth out.
Yes. A straight-on photo of a sketch or flash sheet works well. Crop it tight before uploading so the design fills the frame, and pick Linework mode to keep the interior lines of the drawing.
A true-size tiled print PDF for Letter or A4 thermal stencil paper, an exact-size PNG at 300 DPI, and an SVG. The PDF includes overlap, registration marks, page numbers, and a 1-inch calibration square so the printed stencil matches the size you set.
