Barcode Generator

Barcodes encode short strings of data — a product number, a serial code, an inventory ID — into a pattern of bars that a scanner can read instantly and without typos. Different symbologies exist for different jobs: retail products use EAN-13 or UPC, logistics and internal systems often use CODE128 or CODE39, and pharmacies use Pharmacode. Picking the right format matters because each one accepts a different character set and length.

This generator supports over twenty symbologies: CODE128 (with explicit A/B/C subsets), CODE39, CODE93, EAN-13, EAN-8, the EAN-5/EAN-2 supplements, UPC-A, UPC-E, ITF, ITF-14, MSI and its check-digit variants (MSI-10/11/1010/1110), Codabar, and Pharmacode. For EAN and UPC codes it shows the mod-10 check digit live as you type. You can build a single barcode or a whole batch at once, adjust bar width, height, and whether the human-readable value is printed, then export as a crisp PNG, a scalable vector SVG, a print-ready PDF, or copy the image straight to your clipboard. Bulk mode turns a list of values into a sheet of barcodes in one step.

Everything runs in your browser. The values you type and the barcodes you generate are never uploaded to a server, so the tool works offline once loaded and keeps your product or inventory data private.
