How to use Bulk QR Code Generator
Generate hundreds of QR codes at once from a CSV file or pasted list — all processed in your browser with no data uploaded to any server. Ideal for product labels, conference badges, event tickets, loyalty cards, and inventory management. Download all codes as individual files in a ZIP archive, ready for printing.
- Prepare a CSV file with one URL or text value per row (or paste a list).
- Upload the CSV or paste your list into the input area.
- Configure shared settings: size, error correction, file format (SVG or PNG).
- Click "Generate All" — QR codes are created sequentially in the browser.
- Download all codes as a ZIP archive with filenames based on the input values.
Your data never leaves your device — 100% private processing.
CSV format and field mapping
A simple CSV with one column of URLs or text values works out of the box. For named files, use a two-column CSV: the first column is the filename (without extension), and the second is the content to encode. Advanced mode supports additional columns for per-QR settings like colors or error correction level. UTF-8 encoding is required for non-ASCII characters like accented letters, CJK characters, or emoji.
Performance at scale
Browser-based batch generation can produce approximately 200–500 QR codes per minute depending on the device and QR complexity. For batches over 1,000 items, the process runs in a Web Worker to keep the UI responsive, with a progress bar showing completion percentage. SVG files are slightly faster to generate than PNG files. For enterprise-scale batches (tens of thousands), a server-side solution will be more appropriate.
| Batch size | Estimated time | Recommended format | Notes |
|---|---|---|---|
| 1–50 | <5 seconds | SVG or PNG | Instant for most devices |
| 51–500 | 10–60 seconds | SVG preferred | Progress bar shown |
| 501–2,000 | 1–5 minutes | SVG | Web Worker keeps UI responsive |
| 2,001–10,000 | 5–25 minutes | PNG (smaller files) | Consider server-side for speed |
| 10,000+ | Very slow | Server-side solution | Not recommended in browser |
