Generate professional DMC color-coded diamond painting patterns from any photo. Choose from 40+ canvas sizes, 457 DMC colors, and round or square drills. Completely free — no sign-up, no watermarks, no download required.
Features
Professional-grade tools typically reserved for commercial diamond painting suppliers — available free in your browser.
Every color in your pattern is matched to its official DMC drill code using perceptual color distance — the same technique used by professional color scientists.
Choose from A4, A3, 30×40cm, 40×50cm, 50×70cm, 50×80cm and more — or enter fully custom dimensions. Bead counts update in real time.
Switch between 2.8mm round and 2.5mm square drill types. The tool adjusts grid density and bead count calculations automatically.
Paint, erase, fill bucket, eyedropper, and color-replace tools let you fine-tune your generated pattern before exporting.
Download your pattern as a print-ready high-resolution PNG image with grid lines, symbols, and color key. Save project files to continue editing later.
All processing happens locally in your browser. Your photos are never uploaded to any server. Works offline after initial page load.
