There's no strict limit, but for optimal performance, we recommend batches of 1000 QR codes or fewer. Larger batches may take longer to process and download.

Use a simple CSV with column headers. Each row will generate one QR code. You can include columns like name, phone, email, website, company, or any text data. Download our sample template for the correct format.

Yes! You can mix URLs, plain text, email addresses, phone numbers, and any other data types in a single batch. Each row will be converted to its appropriate QR code format.

You can download QR codes in PNG (for images), SVG (for vector graphics), or PDF format. All codes are packaged in a ZIP file for easy bulk download.

Enter a URL pattern with {n} as a placeholder (e.g., https://mysite.com/page-{n}), set start and end numbers, and we'll automatically generate sequential URLs for batch QR code creation.

Yes! You can adjust the size, colors (foreground and background), error correction level, and file format for all QR codes in the batch.

No, all processing happens in your browser. Your CSV files and generated QR codes are not stored on our servers, ensuring complete privacy and security.

Higher error correction allows QR codes to be readable even if partially damaged. Low (7%) is fastest, Medium (15%) is recommended for most uses, High (30%) is best for codes that might get damaged or printed on irregular surfaces.
