Barcode Generator

Create scannable barcodes (Code 128, EAN, UPC, and more) for products and assets.

Code 128 accepts letters, numbers and symbols.

Generated in your browser. EAN/UPC formats require exact digit counts (e.g. EAN-13 = 12–13 digits); the value box validates as you type. Always test-scan before mass printing.

About Barcode Generator

Barcode Generator builds scannable barcodes online for inventory, retail labels, and asset tags. Searches for "Code 128 generator", "EAN-13 barcode", "UPC barcode maker", and "free barcode generator" usually need a specific symbology plus a clean downloadable image.

Enter the value to encode, pick a format (Code 128 auto/A/B/C, Code 39, EAN-13, EAN-8, UPC-A, UPC-E, ITF-14, Interleaved 2 of 5, MSI, Pharmacode, Codabar, and related options), then adjust bar height, bar width, and human-readable text under the bars.

Not every string is valid in every format - EAN and UPC expect the correct digit lengths and check digits. Always scan a test print on the device your warehouse or POS actually uses before ordering labels in bulk.

This tool helps you design and export barcodes; assigning official GTINs still follows GS1 and retailer rules when you need globally unique product identifiers.
