About this tool
2D Code Generator is a static, client-side tool with no backend. 2D Code Generator encodes your text into a QR matrix locally with an open-source library and renders it to a canvas.
Because the code is generated on your device, you can encode private links or data without sending them anywhere. Your input never leaves the page, and no account or install is required.
