Which barcode formats are supported?

CODE128, CODE39, EAN-13, EAN-8, UPC-A, and ITF-14 — the most common 1D formats for retail, logistics, and inventory labels.

Is the barcode generated on my device?

Yes. The barcode is rendered entirely in your browser using JavaScript. No data is sent to or stored on our servers.

Can I download the barcode as PNG?

Yes. After you generate a barcode, click Download PNG to save a crisp image file ready for labels, packaging, or print proofs.

When should I use a barcode instead of a QR code?

Use a 1D barcode for retail product codes, warehouse labels, and linear scanners. QR codes are better for URLs, Wi-Fi details, and other 2D data that phone cameras scan easily.

Why does my EAN or UPC barcode fail to generate?

Retail formats require the correct number of digits and a valid check digit. EAN-13 needs 12 or 13 digits; EAN-8 needs 7 or 8; UPC-A needs 11 or 12; ITF-14 needs 13 or 14 digits only.

Is this barcode generator free?

Yes, completely free with no registration required.

Supported barcode formats

CODE128 — flexible alphanumeric encoding for logistics, SKUs, and internal tracking.
CODE39 — widely used in manufacturing and asset tags.
EAN-13 / EAN-8 — European retail product codes on shelf labels.
UPC-A — North American retail barcodes on consumer packaging.
ITF-14 — outer-case and shipping-container barcodes in supply chains.

What is a 1D barcode?

A 1D barcode encodes data as a pattern of vertical bars and spaces of varying widths. Laser and imaging scanners read that pattern to recover the digits or text underneath — making it the standard way to label products, cartons, and assets for fast checkout and inventory tracking.

Common uses

Retail shelf labels — print EAN-13 or UPC-A codes for consumer products.
Warehouse and carton tracking — use ITF-14 on outer-case and shipping labels.
Internal SKUs — encode part numbers with CODE128 for logistics and stock control.
Asset tags — mark equipment and inventory with CODE39 labels.

Runs entirely in your browser

Your data never leaves your device — every barcode is rendered locally with JavaScript, nothing is transmitted or stored on our servers. That makes this tool safe for internal SKUs, draft product codes, and test labels. Need a 2D code for a URL or short message instead? Use our QR code generator.
