This converter is built for batches. It creates a separate QR code for each nonblank line, then lays the codes out on one or more portrait pages. Use two columns for large signs, three for everyday labels, or four for compact tags. The PDF has no watermark, and the text you encode is never fetched or uploaded.
The preview shows the first page before you create anything. A four-module quiet zone is preserved around every QR symbol, and the PDF draws the modules as vector shapes so their edges stay crisp when printed. Captions are optional and are shortened to fit the cell without changing the data inside the code.
