Create scannable barcodes in Code 128, EAN-13, UPC-A, Code 39 and more. Customise size and labels, then download print-ready PNG or SVG.
The Barcode Generator creates scannable barcodes in Code 128, EAN-13, UPC-A, Code 39 and other common formats, rendered directly in your browser as you type the value and choose a symbology. You can adjust bar width, height and label text, then download the result as a print-ready PNG or scalable SVG.
This suits small business owners labelling products, warehouse staff creating internal tracking codes, or anyone needing a one-off barcode without buying dedicated labelling software. Because generation happens locally, there is no limit on how many barcodes you create and no data is sent anywhere in the process.
EAN-13, UPC-A, Code 128 and Code 39 cover most retail and warehouse labelling needs, letting you switch symbology depending on where the barcode will be scanned rather than being locked into one format.
PNG suits quick printing at a fixed size, while SVG scales to any size without losing sharpness, which matters when a barcode needs to appear both on a small label and a larger poster or packaging design.
Because barcodes render entirely in the browser, there is no per-barcode cost or daily limit, making it practical to generate many codes in a row for a full product catalogue.
EAN-13 is the standard for retail products sold outside North America, while UPC-A is the equivalent standard within the United States and Canada. Code 128 is a flexible, high-density format suited to internal logistics and shipping labels, and Code 39 is an older but still widely supported format used in some industrial and library systems.
Print at a large enough size that individual bars stay clearly separated, avoid stretching the image unevenly, and keep the surrounding quiet zone (blank margin) intact, since many scanners rely on that space to detect where the barcode starts and ends. Testing a printed barcode with an actual scanner or phone app before mass-printing labels is good practice.
EAN-13 requires exactly 13 digits and UPC-A requires exactly 12, both including a checksum digit calculated automatically from the rest. Code 128 and Code 39 are more flexible, supporting letters, numbers and some symbols depending on which subset is used.
EAN-13 for retail products outside North America, UPC-A inside it, Code 128 for internal logistics and asset tags, and Code 39 for legacy industrial systems.
For internal stock control, yes. Retail chains require a GS1-issued company prefix, so buy an official number from GS1 before listing products in stores.
