Barcode Generator

Generate CODE128/EAN/UPC barcodes as PNG/SVG.

By EZ4Code Team

Implementation note：Only Code Set B is implemented. This covers ordinary printable characters (ASCII 32–127). Control characters would need Code Set A, and long digit runs are not compressed with Code Set C, so numeric input produces a longer barcode than strictly necessary. Both are optional optimisations in the standard — the encoded symbol itself is fully conformant and scannable.

Frequently Asked Questions

Can I use the generated content commercially?

Yes, all generated content (QR codes, gradients, colors) is free for personal and commercial use.

What output formats are available?

QR codes can be downloaded as PNG or SVG. Gradients generate CSS code. Colors output in HEX, RGB, and HSL.

Can I customize colors and size?

Yes. Every generator exposes its own controls — foreground/background colors, dimensions, and error-correction level for QR codes.

Do the generated QR codes expire?

No. The QR code encodes your data directly into the image, so it keeps working indefinitely and does not depend on any redirect service.
