How to use this tool
Pick a barcode type first — CODE128 for any text or numbers, EAN-13 or UPC for standard retail codes, or CODE39 for the alphanumeric codes used in logistics and asset tags. Type or paste your value into the Value field and the barcode redraws live, while the Bar width, Bar height, and color pickers in the side panel adjust its size and look. Toggle Show human-readable text to include or hide the printed value under the bars, then click Download PNG to save the finished barcode as an image.
