Barcode GeneratorFree online barcode generator
Create Code 128, EAN-13 and UPC-A barcodes for labels, inventory, product mockups and testing. Preview and download the PNG instantly.
Enter the text or numbers you want to encode, choose a barcode type and click generate. This barcode generator creates an instant preview that you can download as a PNG image. Code 128 works well for most general barcode needs because it can encode letters, numbers and many symbols.
Use Code 128 for general labels, inventory codes, asset tags, shipping-style codes, sample barcodes and internal tracking. It is flexible and works with text, numbers and many symbols. Use EAN-13 for 13-digit retail product numbers and UPC-A for 12-digit retail product codes. These numeric formats include a check digit to help detect mistakes.
Yes. After generating the barcode, use the download button to save it as a PNG image. You can place the image in test labels, documents, spreadsheets, inventory mockups or product drafts. For real retail products, make sure you use officially assigned product codes and test the final printed barcode with a scanner.
No. The barcode is generated locally in your browser. The text or number you type is not sent to our server, stored in a database or added to analytics events. This makes the tool useful for quick private testing, label drafts and internal barcode mockups.
Code 128 is a high-density barcode format used for shipping labels, inventory systems, asset tags, warehouse labels and internal tracking. It can represent uppercase letters, lowercase letters, numbers and many common symbols. If you are not sure which format to choose, Code 128 is usually the safest general-purpose option.
EAN-13 uses 13 digits and is common in global retail product identification. UPC-A uses 12 digits and is common in North American retail. Both formats use numeric data and include a final check digit. If you enter 12 digits for EAN-13 or 11 digits for UPC-A, this tool can calculate the final check digit automatically.
You can use this tool to create barcode images, but real retail products usually need officially assigned identifiers from the correct standards organization or product registry. For production use, always verify your code format, print size, contrast and scanner readability before using the barcode on packaging or labels.
You can preview and download a barcode without a scanner. Before using a printed label in a real workflow, however, test it with the scanner and printing setup you intend to use.
