Straight answers

How does the stencil maker work?

Upload a photo or artwork, pick a line mode, and adjust the detail and line weight sliders while you watch the preview update. Set the width in inches, then download a tiled print PDF, a 300 DPI PNG, or an SVG.

What is the difference between the three modes?

Outline traces outer contours for simple, open designs. Linework adds the interior lines, which is what most designs need. Bold thickens every line, useful for blackwork, small text pieces, and stencils that have to stay legible through a long session.

Is the preview really free?

Yes. You can upload, adjust, and preview your stencil before downloading anything. The preview shows the exact lines that will print, so there are no surprises at the printer.
