Qr Code Batch

When One at a Time Isn't Enough

Single QR code generators are everywhere. And for most situations — a restaurant menu, a personal business card, a product landing page — they're perfectly fine.

But if you're a logistics manager tagging 300 inventory items, an events coordinator printing unique attendee badges, a retailer linking individual product SKUs to listing pages, or a teacher creating individual QR codes for 80 student portfolios — doing them one by one isn't a workflow, it's punishment.

The batch QR code generator converts an entire list into individual, named image files packaged in a single ZIP for immediate download.

How to Use It

1. Prepare your list. Open your spreadsheet in Excel or Google Sheets, select the column of URLs or text strings, and copy it. Each cell becomes one QR code.
2. Paste into the tool. One item per line. The tool reads each line as a separate QR code input.
3. Configure options:
   • Output format: PNG (wider support) or WebP (smaller files)
   • Error correction level: Low, Medium, Quartile, or High (see below)
   • QR size: in pixels
4. Generate and download. The browser processes every line locally and packages all generated images into a .zip file, which downloads automatically.

How Files Are Named

Naming 300 QR code files meaningfully is often the hardest part of a bulk generation workflow. The tool handles this automatically:

For an input like https://example.com/product/42:
Output filename: 001_example_com_product_42.png

The sequential zero-padded prefix (001, 002, 045) ensures files sort in the correct order in your file browser. The URL-derived name tells you at a glance what's in each file without having to scan a QR code. For plain text inputs, the first 30 characters of the text are used in the filename.

Understanding Error Correction Levels

QR codes have built-in error correction — they can still be scanned even if part of the code is damaged, dirty, or obscured. There are four levels:

Choose High if you plan to place a logo in the center of the QR code, overlay any graphic, or print on textured surfaces. The extra redundancy keeps the code scannable despite the obstruction.

Common Use Cases

Retail inventory tagging: Generate one QR code per product SKU. Each scans to the product's online listing, management system entry, or spec sheet. Print and attach to physical items.

Event badges and check-in: Each attendee gets a badge with a unique QR code linking to their registration details or check-in form. Generate the full attendee list in one go from your registrations export.

Real estate and property listings: Create QR codes for each property listing URL. Printers can use them on brochures, For Sale signs, or window displays linking to the full online listing.

Library and asset management: Tag physical books, equipment, or tools with QR codes linking to their database records, checkout forms, or status pages.

Education: Generate QR codes for each student's Google Drive folder, portfolio link, or submitted project URL for printed progress reports.

Privacy: Why Local Processing Matters Here

In an enterprise context, the URLs and IDs you're generating QR codes from may be sensitive — internal dashboard links, employee badge IDs, customer portal URLs, internal product SKUs with pricing.

Classic batch generators require you to upload a CSV to an external server, which processes it and returns your files. That means your entire dataset passes through a third-party system.

This tool processes everything in your browser's memory. The list you paste never leaves your device. The ZIP is assembled locally and downloaded directly — no external server involved.

Frequently Asked Questions

How many QR codes can I generate at once? There's no hard limit set by the tool. In practice, browser memory limits apply for very large batches. Most users generate up to 1,000 codes without issues; batches of several thousand may slow down depending on your device.

Can I generate vCards or WiFi QR codes in bulk? Currently the tool processes one QR type per batch — text or URL. vCard and WiFi formats require structured inputs that don't import cleanly from a spreadsheet column. Support for structured formats may be added in future versions.

What's the maximum data a QR code can hold? The QR standard supports up to 4,296 alphanumeric characters or 2,953 bytes. Long URLs (especially tracking URLs with many parameters) should still fit. Very long strings may generate denser, harder-to-scan QR codes — keep URLs concise where possible.
