Loading Barcode Generator…
Barcode Generator creates scannable barcodes from your data in common formats, with a print-ready image download, for products, inventory, labels, and asset tracking.
It helps to know when a barcode (versus a QR code) is right: a traditional 1D barcode encodes a short number read by laser scanners, perfect for product SKUs and inventory, whereas a QR code holds richer data like URLs and is read by cameras. For item numbers and stock, the barcode is the tool; for links and text, the QR Code Generator fits better.
Format and registration matter for retail. EAN/UPC barcodes used in shops require numbers registered through GS1 to be valid commercially, while internal uses (your own inventory, labels, assets) can encode any code with formats like Code 128 or Code 39. So the image is free to generate here; a registered retail number is a separate step.
For reliable scanning, print at adequate size with strong black-on-white contrast and a clear margin, and test-scan before a big run. Generation runs in your browser with nothing uploaded and no watermark. Pair it with the QR Code Generator and other ToolsMonk business tools.
