How to Generate Multiple QR Codes at Once: The Complete Batch Generation Guide

Need to create QR codes for 100 products? 500 event tickets? 1,000 employee badges? Manually generating them one by one would take hours—or even days.

That's where batch QR code generation comes in. With Codex QR's batch processing feature, you can generate hundreds or even thousands of QR codes in seconds from a simple CSV or TXT file.

What is Batch QR Code Generation?

Batch QR code generation (also called bulk or mass QR code creation) is the process of creating multiple QR codes simultaneously from a list of data. Instead of:

• Opening the generator
• Entering data for QR code #1
• Generating and saving it
• Repeating 99 more times...

You simply upload a file with all your data, click generate, and get all 100 QR codes ready to use in seconds.

Why Use Batch QR Code Generation?

1. Save Massive Amounts of Time

Creating 100 QR codes manually might take 2-3 hours. With batch generation, you're done in under a minute. That's a 99% time savings.

2. Reduce Human Error

When entering data manually for hundreds of QR codes, typos are inevitable. Batch generation from a spreadsheet ensures every QR code is accurate.

3. Maintain Consistency

All QR codes are generated with the same settings—resolution, colors, error correction, margins. No variations from fatigue or distraction.

4. Scale Your Projects

Need 10 QR codes? 100? 1,000? The effort is the same. Batch generation scales effortlessly.

Common Use Cases for Batch QR Codes

Here are some real-world scenarios where batch QR code generation is essential:

Events & Conferences

Generate unique QR codes for every attendee ticket, each linking to their registration details or personalized agenda.

Product Inventory

Create QR codes for every product in your catalog, linking to product pages, manuals, or warranty information.

Marketing Campaigns

Generate tracking QR codes for print materials, each with unique UTM parameters to measure campaign performance.

Educational Materials

Create QR codes for every chapter or resource in a textbook, linking students to supplementary videos or exercises.

Employee Badges

Generate vCard QR codes for every team member's contact information.

Real Estate Listings

Create unique QR codes for every property, linking to virtual tours or listing details.

How to Generate Multiple QR Codes in Codex QR

Codex QR makes batch generation incredibly simple. Here's the step-by-step process:

Step 1: Access Batch QR Generation

Open Codex QR and click Generate QR from the home screen. In the top-right corner, you'll see a Batch QR button—click it.

Step 2: Prepare Your Data

You can import data in two formats:

CSV File (Recommended)

Create a CSV file with your data. The first row should be headers, and each subsequent row is one QR code.

Example for URLs:

url
https://example.com/product-1
https://example.com/product-2
https://example.com/product-3

Example for vCards:

name,email,phone
John Doe,john@example.com,+1234567890
Jane Smith,jane@example.com,+0987654321

TXT File (For Simple Lists)

For simple text or URL QR codes, a plain text file works too—one entry per line:

https://example.com/product-1
https://example.com/product-2
https://example.com/product-3

Step 3: Import Your File

In the Batch QR screen, click Import CSV/TXT and select your file. Codex QR will automatically parse the data and show you a preview.

Alternatively, you can paste content directly into the text area if you have your data in your clipboard.

Step 4: Review the Preview

Codex QR shows you a live preview of the QR codes being generated. This lets you verify that:

• The data is parsed correctly
• QR codes are scannable
• The format looks good

You'll see the total count of QR codes that will be generated and can scroll through the preview list.

Step 5: Generate All QR Codes

Click the Generate All button. Codex QR processes your entire list using parallel processing to maximize speed.

For 100 QR codes, this typically takes 5-10 seconds on a modern Mac. For 1,000 QR codes, expect 30-60 seconds.

Step 6: Export Your QR Codes

Once generation is complete, click Save All. Choose a folder, and Codex QR will export all QR codes as individual PNG files.

Files are automatically named based on your data (e.g., product-1.png, product-2.png) to keep everything organized.

Pro Tips for Batch QR Generation

1. Use Descriptive Filenames

Include meaningful identifiers in your CSV data. Instead of generic URLs, use: https://example.com/event-ticket-12345

2. Test with a Small Batch First

Before generating 1,000 QR codes, create a test batch of 5-10 to verify your data format and settings are correct.

3. Choose the Right Resolution

For print materials, use at least 512x512 pixels. For digital displays, 256x256 is usually sufficient. Adjust in Settings before batch generation.

4. Consider Error Correction

If QR codes might get damaged or partially obscured, use a higher error correction level (H = High) in Settings. This makes codes slightly larger but more resilient.

5. Organize Your Output

Create separate folders for different batches or projects. For example: /QR-Codes/Summer-Event-2026/ /QR-Codes/Product-Catalog-Q1/

Performance: How Fast is Batch Generation?

Codex QR uses parallel processing optimized for your Mac's CPU. Here are typical generation times:

• 100 QR codes: 5-10 seconds
• 500 QR codes: 20-30 seconds
• 1,000 QR codes: 40-60 seconds
• 5,000 QR codes: 3-5 minutes

Processing is limited to your CPU core count to prevent system slowdowns, ensuring your Mac remains responsive during generation.

Data Privacy: Everything Stays Local

Unlike online batch QR generators that upload your data to remote servers, Codex QR processes everything locally on your Mac.

This means:

• ✅ Your data never leaves your device
• ✅ No internet connection required
• ✅ Complete privacy for sensitive information
• ✅ Works offline at events or secure locations
