Why use GenerateQuick's Barcode Generator?
Our free Barcode Generator supports seven professional barcode standards: CODE128 for any ASCII text, EAN-13 for international retail products, UPC-A for the US market, CODE39 for alphanumeric inventory labels, ITF-14 for outer shipping cartons, MSI for warehouse management systems, and Pharmacode for pharmaceutical packaging. All barcodes are generated instantly in your browser using the JsBarcode library, with no uploads, no data transmitted, and no sign-up required.
Both PNG and SVG downloads are available. SVG barcodes are fully scalable vector graphics that can be placed at any size in print files, laser cutters, or design tools without any pixelation. Use our barcode generator for product labels, shelf labels, event tickets, asset tags, shipping documentation, and any application where a machine-readable code is required.
Frequently Asked Questions
What barcode format should I use for retail products?
EAN-13 is the international standard for retail products sold outside the United States. UPC-A is the standard for US and Canadian retail. Both require a valid GTIN (Global Trade Item Number) issued by a licensing body such as GS1 before they can legally be used on commercial products.
Can I use CODE128 for inventory and shipping labels?
Yes. CODE128 encodes the full ASCII character set, including letters, numbers, and symbols, making it the most flexible choice for internal inventory labels, warehouse tracking, and shipping documentation where standard retail compatibility is not required.
Do these barcodes expire?
No. Barcodes are static PNG or SVG image files that encode your exact value permanently, with no connection to any online service or server. The barcode will scan correctly for as long as the physical label or printed image remains readable.
Is my data sent to a server when generating barcodes?
No. Barcodes are generated entirely in your browser using the JsBarcode open-source library. No data is uploaded, logged, or transmitted to any server.
