Customization Options
Adjust the bar width and height with sliders. Toggle text visibility below the barcode, choose a font size, and pick custom colors for both the bars and background. These options let you match the barcode to your label or packaging design.
Download & Export
Download your barcode as a high-resolution PNG image for print or a scalable SVG file for web and professional design workflows. Both formats are generated entirely in your browser — no data is sent to any server.
Frequently Asked Questions
What barcode format should I use?
For general use, CODE128 is the most versatile — it supports letters and numbers. For retail products, use EAN-13 (international) or UPC-A (North America). For shipping cartons, ITF-14 is the standard. CODE39 is common in logistics and government applications.
How many digits do EAN and UPC barcodes require?
EAN-13 needs 12 or 13 digits, EAN-8 needs 7 or 8 digits, and UPC-A needs 11 or 12 digits. If you enter one fewer digit, the check digit is calculated automatically. If you include the check digit, it must be correct or the barcode will fail validation.
Can I use this barcode for commercial products?
This tool generates standard barcode images, but you still need a valid GS1 company prefix to use EAN or UPC codes on retail products. The barcode itself is just a visual encoding of the number you provide.
Is the barcode generated on a server?
No. The barcode is generated entirely in your browser using JavaScript. No data is uploaded to any server. Your input stays private on your device.
What is the difference between PNG and SVG downloads?
PNG is a raster image at 2x resolution, suitable for printing and general use. SVG is a vector format that scales to any size without losing quality, making it ideal for professional print workflows and graphic design software.
