Barcode Generator

A barcode is a pattern of bars that stores a short value, such as a product number, in a form a scanner can read. Real barcode standards define exact bar patterns, checksums and quiet zones, and a pattern that does not follow a standard may not scan.

This tool draws bars from your input using a simple deterministic pattern in your browser, with the value printed below, and lets you download the image. It is honest about its limit: the bars are visual only, and they have not been verified as a scannable barcode standard.

How to Use This Tool

1. Enter your text or numbers: type the value you want shown below the bars.
2. Click Draw Barcode: the bars appear on a white canvas with your value below them.
3. Click Download Image: save the bars as a PNG image.
4. Test before real use: if you need a barcode for real products or labels, test scanning first, and use a verified standard barcode tool for production.

Good Practice Tips

• Do not use this for real products yet: unverified bars may fail at a checkout scanner.
• Keep values short and clear: short numbers print more clearly below the bars.
• Print at a good size: tiny bars on a small label are harder to see and harder to scan.
