About the Barcode Generator
Code 39 is the workhorse barcode of warehouses, libraries and ID badges: it encodes uppercase letters, digits and a few symbols, and every scanner reads it. Type your text and this generator draws the barcode with proper start/stop characters, lets you tune the bar width and height for your label stock, and exports a crisp PNG or scalable SVG for printing. Check the human-readable line to make labels people can verify too.
