About Barcode Generator
The Barcode Generator creates one-dimensional barcodes from text or numbers. Choose a format (CODE128, CODE39, EAN-13, EAN-8, UPC-A, ITF-14, MSI, Pharmacode), and set height, bar width, colors, and whether the text shows below it.
Each format has its own length/charset rules (e.g. EAN-13 needs 12–13 digits) — an error message appears if the value is invalid. Preview live and download as PNG or SVG. Processed entirely in the browser.
FAQ
Is any data sent to a server?
