Which format should you choose for your project?
The world of barcodes is vast and highly standardized. Here is a quick guide to choosing the right symbology (format) for your use case:
2D Codes (Matrix)
2D codes store data in two dimensions (horizontally and vertically), allowing them to hold hundreds of times more information than a classic linear barcode.
- QR Code: The global standard for consumers. Ideal for sharing URLs, free text, vCards, or setting up WiFi. Highly resilient thanks to its error correction.
- Data Matrix: Often confused with QR, but different. It is the standard for heavy industry and healthcare. It can be laser-engraved onto extremely small electronic components.
- Aztec: Its unique feature is that it does not require a blank "quiet zone" around the code. It is the standard for transport ticketing (train tickets, airline boarding passes).
1D Retail Barcodes
These codes are scanned at supermarket checkouts.
- EAN-13: The retail standard for Europe and the rest of the world. It requires 13 digits. Pro Tip: Our tool will automatically calculate the 13th control digit (checksum) if you only enter 12.
- UPC-A: The retail standard for North America (12 digits).
1D Industrial Barcodes
- Code 128: The king of industry. Highly dense, it can encode any ASCII character (uppercase/lowercase letters, numbers, punctuation). It is the best choice for internal use.
- ITF-14: Mandatory for printing barcodes on corrugated cardboard (the large packaging boxes containing multiple EAN-13 products inside).
High-Resolution Export
Once your code is generated, don't settle for a low-quality screenshot. Use our SVG export option. The vector SVG format ensures the barcode will maintain mathematically perfect edges, whether it's printed on a tiny 1-inch label or a massive billboard.
Frequently Asked Questions
Q: Is barcode-2d-code-generator free to use?
R: Yes, the barcode-2d-code-generator utility is 100% free. All tools on Dolf.in are accessible at no cost and without intrusive ads.
Q: Is my data secure?
R: Absolutely. Dolf.in uses a 'Serverless' approach: your data is processed locally in your browser and is never sent to our servers.
Q: Do I need to install any software?
R: No, no download or installation is required. Everything works directly in your web browser.
Q: Can I use these barcodes for my products in stores?
R: Yes, the generated EAN-13 and UPC-A formats strictly comply with retail industry GS1 standards. However, remember that to sell a product in the real world, you must first purchase an official GTIN from the GS1 organization.
Q: What is the difference between a QR Code and a Data Matrix?
R: The QR Code is widely used in marketing and can hold a lot of data. The Data Matrix is optimized for storing maximum data in an extremely small physical space (high density), making it very popular in manufacturing, logistics, and healthcare.
