Free Stained Glass Pattern Maker
Free stained glass pattern maker. Convert any photo into thick, closed-loop outlines perfect for glass art, soldering lines, and decorative windows.
The Stained Glass Pattern Maker transforms any photograph into a template suitable for stained glass, mosaic, and decorative glass projects. Our specialized algorithm creates clean, closed-contour line art that mirrors the bold outlines of traditional leaded glass artwork.
Closed Contour Technology
The critical difference between generic line art and stained glass patterns is contour closure. In stained glass, every piece of glass must be fully enclosed by lead came or copper foil. Our algorithm applies morphological closing operations to ensure that all outlines form continuous, unbroken boundaries — no gaps where solder would fail.
Adjustable Line Weight
The line weight control lets you match the thickness of your pattern lines to your preferred came width. Thicker lines suit H-channel lead came, while thinner lines work for copper foil techniques.
How to Create Your Pattern
Upload a photograph of your desired subject — a flower, bird, landscape, or portrait. Our adaptive threshold algorithm extracts the major shapes and contours. Adjust the intensity to control detail level: lower values produce simpler patterns with fewer pieces (ideal for beginners), while higher values capture more intricate details for advanced artisans.
Print and Transfer
Download the high-contrast PNG output and print at your desired size. Use it as a cutting template under your glass, or trace it onto pattern paper. The pure black lines on white background ensure maximum visibility through translucent glass.
