Free Bar Code Generator - Create QR Codes & Barcodes Instantly

Why Use Our Free Bar Code Generator?

Looking for a reliable way to create barcodes without the hassle? You've come to the right place. Whether you need a single QR code for a business card or you're running a bulk bar code generator job for inventory management, this tool handles it all. We built this because we were tired of complicated barcode software that required installations, subscriptions, or technical knowledge.

This free bar code generator supports all the major formats you actually need: QR codes for modern applications, Data Matrix for compact encoding, Code 128 for general use, and retail standards like UPC-A and EAN-13. The best part? You see exactly what you're getting with the live preview before downloading anything.

Perfect for Bulk Bar Code Generation

Need to create hundreds or thousands of barcodes? The bulk bar code generator feature lets you paste a list or upload a CSV file, and within seconds you'll have a PDF or ZIP file with all your codes ready to print. We've used this ourselves for everything from product labeling to event ticketing, and it just works. No limits, no watermarks, no premium upsells.

Customizable Label Sizes

One size definitely doesn't fit all when it comes to labels. That's why we added support for the most common label sizes - from small 2×2 inch squares perfect for product labels to larger 4×6 inch formats for shipping labels. The text automatically adjusts to look right at any size, so you don't have to fiddle with settings. All labels are generated at 300 DPI for crisp, professional printing quality.

How to Use This Bar Code Generator

For single barcodes: Just type what you want to encode, pick your format and size, and watch the preview update in real-time. When it looks good, download it as PNG, JPG, or PDF. Takes about 10 seconds.

For bulk generation: Either paste your list (one item per line) or upload a CSV file with your data. Choose whether you want text labels below each code, pick your size, and generate. You'll get either a PDF with all codes or a ZIP file with individual images. We've generated batches of 10,000+ codes without any issues.

When to Use Different Barcode Types

QR Codes: Great for URLs, contact info, WiFi passwords, or any text you want people to scan with their phones. Most versatile option.

Data Matrix: Super compact, perfect when space is limited. Used a lot in electronics and small parts marking.

Code 128: The workhorse of warehouse and shipping. Handles both numbers and letters, good scanner compatibility.

UPC-A / EAN-13: Retail standards. If you're selling products in stores, you'll need these.

Completely Free, No Catch

Seriously, it's free. No account required, no email signup, no limits on how many you generate. We believe tools like this should just be available. Create one barcode or generate thousands in bulk - it's all the same to us. The only thing we ask is that if you need actual label printing services, consider checking out the folks we work with.

Tips for Best Results

Print Quality: All labels are created at 300 DPI, which is perfect for most label printers and standard inkjet/laser printers.

Label Size: Match the size you select here with your actual label sheets. Standard 2×2 inch labels work great for most products and assets.

CSV Format: For bulk uploads, just put one barcode value per row in the first column. Excel or Google Sheets can export to CSV format.

Testing: Generate a single label first to make sure it scans properly before running a large batch. Different scanners can be picky about contrast and size.
