About Barcode Generator

Barcodes are machine-readable representations of data using parallel lines, dots, or other geometric patterns. They are used across countless industries — from retail product labeling (EAN, UPC) to logistics and shipping (ITF-14, CODE128), library management (Codabar), and pharmaceutical packaging (Pharmacode).

Our Barcode Generator lets you create high-quality barcodes in 16 different formats directly in your browser. Customize dimensions, colors, and text display, then download as a crisp PNG image or copy to your clipboard. All processing happens locally — no data is sent to any server.

Frequently Asked Questions

What is a Barcode Generator? expand_more
A barcode generator is a tool that converts text, numbers, or other data into a scannable barcode image. The generated barcode can be printed on labels, packaging, or documents and read by barcode scanners or smartphone apps.
Which barcode format should I use? expand_more
CODE128 (Auto) is the most versatile and supports all ASCII characters — use it if you are unsure. For retail products, use EAN-13 (international) or UPC-A (US/Canada). For shipping containers, use ITF-14. For pharmaceutical use, choose Pharmacode.
Is my data secure? expand_more
Yes. This tool runs entirely in your browser. Your data never leaves your device and is not sent to any external server, ensuring complete privacy.
Can I customize the barcode colors? expand_more
Absolutely. You can change both the background color and the barcode line color using the color pickers. Just make sure there is enough contrast between the two colors for scanners to read the barcode reliably.
Why does my barcode show an error? expand_more
Different barcode formats have specific input requirements. For example, EAN-13 requires exactly 12 or 13 digits, and UPC-A requires 11 or 12 digits. Check the format description below the dropdown for guidance on valid input.
