LOCAL QR CHART TOOL

QR Code Bead Pattern Maker

Turn a link or UTF-8 text into a two-color fuse-bead matrix. Your text stays in this browser; the pattern, material list and exports use one matrix.

Build the chart

Load colors, then generate a current chart.

No current PNG verification.

Text is encoded exactly as entered (up to 8,192 UTF-8 bytes). QR capacity and the 160 × 160 bead-grid limit may be reached sooner. It is never sent to a server.

Materials

Generate a chart to calculate materials.

    The full bead width is W = (n + 2q) × s: QR modules n, quiet-zone modules q, and beads per module s. Finished width is W × pitch mm. The material total includes every light border bead.

    Brand color names and screen colors are approximate. Contrast, fusing, phone camera, lighting, distance and angle can all affect a physical result. Test your fused piece with your own phone in its intended light; this page does not predict physical scanning.

    Each PNG is locally decoded again from its encoded pixels and reports the result. A missing, mismatched or decoding-error state is not a pass.

    Try the photo-to-bead converter, pixel art converter, or our color and data guide for different pattern tasks.
