Barcode Generator

The tool supports CODE128, EAN-13, EAN-8, UPC-A, CODE39, ITF-14, MSI, Pharmacode, and Codabar. The one you will reach for most often is CODE128 because it can encode any ASCII character and is the standard for shipping labels, inventory systems, and general-purpose labeling. If you are working in retail, you probably need EAN-13 (international products) or UPC-A (North American products), and those have strict digit requirements with a check digit built in. CODE39 is popular in manufacturing and government because it is older and widely supported, though it produces longer barcodes. ITF-14 is specifically for outer carton labeling in logistics. Pharmacode is a niche one used in pharmaceutical packaging. My recommendation: if you are not sure which format to use and you just need something that works, go with CODE128. It handles the widest range of input and most scanners support it.

Yes, every barcode this tool generates is fully standards-compliant and will scan with any barcode reader, whether that is a handheld laser scanner, a phone camera app, or a built-in scanner on a POS terminal. The tool renders barcodes using the JsBarcode library, which follows the exact specifications for each format including proper quiet zones, bar width ratios, and check digits where required. I have used these for inventory labels, event tickets, and product packaging without any issues. One tip: when you download the PNG, make sure you print it at a reasonable size. If you scale a barcode down too small, the bars can blur together and some cheaper scanners will struggle with it. For printing, I would keep the barcode at least one inch wide for reliable scanning. You can also increase the resolution in your print settings for crisper bars.
