How to use this tool
- Enter your message
Use a short URL or plain text. Choose error correction and beads per module.
- Generate and check
Generate QR runs a digital decode check. The light border is part of the design; do not remove it.
- Build in sections
Read the color key and assembly map. Work from the top-left board, save a project, and test a small section before fusing.
Frequently asked questions
Will the finished bead QR always scan?
No digital check can guarantee a physical result. Bead holes, uneven melting, glare and contrast affect recognition. Test with your phone before and after fusing.
Why is the white border filled with beads?
The QR needs a continuous light quiet zone at least four modules wide. White beads are counted and should stay in the physical design.
Can I print the PDF at actual bead size?
The PDF is a numbered reference chart with 4 mm cells, not a full-size ironing template. Large boards are split across pages with coordinates. Physical size estimates use the peg pitch you enter.
Can I edit the QR pattern by hand?
The QR grid is protected from painting so its structure stays intact. Change the message or module scale and generate again. Downloads are checked for digital readability.
Are my images or projects uploaded?

Rectangular square-peg grids only. No shaped or staggered boards. Pitch defaults are starting points, not verified board specifications. Follow your bead manufacturer’s age guidance and fusing instructions.
