Customize the Appearance (Optional)

Use the sliders to adjust bar width (1px to 4px) and bar height (50px to 200px) to fit your label size. Toggle text display on or off and adjust font size (10px to 24px) if text is enabled. Every change reflects instantly in the live preview panel.

Which barcode formats does this tool support?

Down Arrow
The tool supports 8 formats: Code 128 (alphanumeric, general purpose), EAN-13 (retail, 13 digits), UPC-A (US retail, 12 digits), Code 39 (industrial and logistics), ITF-14 (shipping containers, 14 digits), Codabar (libraries and blood banks), MSI (inventory control), and Pharmacode (pharmaceutical packaging). A format-specific hint below the input tells you exactly what data each one accepts.

What download formats are available?

Down Arrow
You can download your barcode in three formats: PNG (a high-resolution image at 2x scale, great for printing on labels), SVG (a scalable vector file that looks sharp at any size, ideal for packaging and print design), and PRN (a ZPL file for Zebra and other thermal label printers). You can also click Copy to paste the SVG code directly into your design tool.

What is a PRN file and which printers support it?

Down Arrow
A PRN file contains ZPL (Zebra Programming Language) commands that thermal label printers understand directly. Zebra printers (like the ZT and GK series) are the most common. Other brands like Honeywell and Bixolon also support ZPL. This format is popular in warehouses and retail stores for printing labels without using a PC driver.

Can I customize the barcode size and appearance?

Down Arrow
Yes. You can adjust bar width (1px to 4px), bar height (50px to 200px), and toggle the text label below the barcode on or off. When text is enabled, you can also adjust the font size (10px to 24px). Every change updates the preview instantly.

Is my data safe when I use this barcode generator?

Down Arrow
Yes, your data is fully private. All barcode generation happens inside your browser using client-side JavaScript. The product codes, SKUs, or text you enter are never sent to any server. Your data stays on your device only.

What barcode format should I use for retail products?

Down Arrow
For retail products sold in stores, EAN-13 (used across India and most of the world) or UPC-A (used in the US and Canada) are the standard choices. For internal inventory, shipping, or general use, Code 128 is the most flexible and widely supported format.

Can I use the generated barcodes commercially?

Down Arrow
Yes. Barcodes generated with this tool can be used for internal inventory tracking, warehouse labels, shipping slips, and price tags. For EAN-13 or UPC barcodes that need to be scanned at retail checkouts across multiple stores, you should register an official GS1 barcode to ensure global uniqueness.
