Design & Patterns

The Science of Symbology

Choosing the correct standard for your specific use case.

EAN & UPC

The standard for retail products worldwide. EAN-13 is used globally, while UPC-A is the primary standard in the United States and Canada.

Code 128

A high-density barcode that supports all 128 ASCII characters. It is the most versatile format for internal inventory and logistics.

Contrast & Quiet Zones

Scanners rely on the "Quiet Zone"—the white space at either end of the code. Our generator automatically includes safe margins for faster reads.

Checksum Validation

Many standards (like EAN) include a final "check digit" calculated from the previous numbers to ensure the scanner didn't misread the code.

Universal Accessibility

Our tools are built with WCAG standards in mind, ensuring a seamless experience for users across all devices and assistive technologies.

Data Privacy First

We process all data locally in your browser whenever possible. Your sensitive information never touches our servers.

Frequently Asked Questions

Resolving technical concerns about printing and scanning.

Can barcodes be read by modern smartphones?
Yes! Modern camera-based scanners (including iPhone and Android) use sophisticated image processing and can read all the formats generated by this tool perfectly.
What is the best resolution for printing?
We recommend downloading the PNG/SVG and printing at 300 DPI or higher. Avoid using low-quality inkjet printers that might "bleed" ink into the white spaces.
Can I use my own colors?
While we support custom colors, black bars on a white background provide the highest contrast. Dark blue or green can work, but red should be avoided as many scanners use red lasers.
Is this tool free to use for commercial projects?
Yes, all our tools are free for both personal and commercial use. You can generate assets for your business, clients, or side projects without any licensing fees.
