Barcode Generator

Generate a scannable barcode from any text or number — free, instant, and downloadable.

Overview

What is a barcode generator?

A barcode generator encodes text or numbers into a series of parallel bars that a barcode scanner or camera app can read back into the original value — used across retail, logistics, and inventory management.

This tool generates Code128 barcodes, a widely supported format capable of encoding letters, numbers, and symbols in a single compact code, readable by virtually any standard barcode scanner.

Tips

Best practices to keep in mind

A few things worth knowing before printing a barcode.

Code128 (the default format here) can encode any letters, numbers, and most symbols — if you specifically need EAN, UPC, or another retail format, check that your scanning system supports the format you generate.
Always test a printed barcode with a real scanner before relying on it — some scanners are stricter about quiet-zone margins and print quality than others.
Don't shrink a barcode below the minimum readable width for your scanner — bars that are too thin or too close together are the most common cause of failed scans.
Print barcodes on a printer with sufficient resolution (300 DPI or higher) — low-resolution printing can blur adjacent bars together and make the code unreadable.

FAQs

Frequently asked questions

Have questions about generating barcodes? Here are the most common ones our users ask before getting started.

Is this barcode generator free to use?

Yes, the barcode generator is completely free with no signup, no usage limits, and no watermarks on the output. It runs entirely in your browser, so there are no server costs passed on to you and no account is ever required to generate a barcode.

Does my content get uploaded to a server?

No. The barcode is generated locally in your browser using JavaScript — whatever text or number you enter never leaves your device or gets transmitted to any server. This makes the tool safe to use with internal product codes or private inventory data.

What barcode format does this tool use?

This tool generates Code128 barcodes, one of the most widely supported formats, capable of encoding letters, numbers, and most symbols in a single compact barcode. It's commonly used in shipping, logistics, and general-purpose inventory systems.

Can this barcode be scanned by any standard barcode scanner?

Yes — Code128 is supported by virtually all modern barcode scanners and scanning apps, including smartphone camera scanner apps. As long as the barcode is printed clearly with adequate size and contrast, it should scan reliably on standard retail and warehouse scanning equipment.

What's the best way to print a barcode without breaking it?

Keep the barcode at a reasonable size rather than shrinking it too small, print at 300 DPI or higher for crisp bar edges, and leave a blank quiet zone on either side. Avoid stretching the image non-proportionally, since that distorts the bar widths and can prevent scanners from reading it correctly.
