Bulk QR Code Generator
Generate multiple QR codes
Frequently Asked Questions
How do I generate QR codes in bulk?
Upload a CSV or text file with one URL or data entry per line. The tool generates individual QR code images for each entry. You can download all codes as a ZIP file. Supports hundreds of QR codes in a single batch with consistent size and error correction.
What file format should I use for bulk QR code input?
CSV format with one data entry per row. Column A: the data to encode (URL, text, etc.). Optional Column B: filename for the output image. The tool also accepts plain text files with one entry per line. Maximum recommended: 500 entries per batch.
What output formats are available for bulk QR codes?
PNG (recommended for web and print), SVG (scalable vector, ideal for large prints), PDF (one QR per page or grid layout). All formats support custom sizes from 100×100 to 2000×2000 pixels. The ZIP download organizes files by the input data or custom filenames.
How do I create QR codes for product inventory labels?
Prepare a CSV with product IDs or URLs. Set consistent size (300×300 px minimum for labels). Use high error correction (Level H, 30%) for durability. The tool generates labeled QR codes that can be printed on adhesive label sheets.
What is the maximum data each QR code can hold?
QR codes hold up to 4,296 alphanumeric characters or 7,089 numeric digits. For URLs, keep under 300 characters for reliable scanning. Higher data = denser QR code = harder to scan at small sizes. The tool warns if data exceeds recommended limits.
