Frequently Asked Questions
What barcode formats are supported?
This tool supports three widely-used barcode formats: Code128 for general-purpose ASCII text encoding, EAN-13 for retail product identification with 13 digits, and Code39 for alphanumeric data commonly used in logistics and inventory.
What is the difference between Code128, EAN-13, and Code39?
Code128 encodes the full ASCII character set and is compact and versatile. EAN-13 encodes exactly 13 digits and is the global standard for retail products. Code39 supports uppercase letters, digits, and a few special characters, making it popular in non-retail industries.
How do I create a valid EAN-13 barcode?
Enter exactly 12 or 13 digits. If you enter 12 digits the check digit is calculated automatically. If you enter 13 digits the tool validates the check digit for you. The barcode will not render if the input contains non-numeric characters.
Can I download the barcode as an image?
Yes. You can download the generated barcode as a PNG image or as an SVG vector file. SVG is ideal for print materials because it scales without losing quality at any size.
Is my data safe?
Yes! All processing happens entirely in your browser. Your data is never sent to any server. No data is collected, stored, or transmitted.
