What is a barcode?
A barcode encodes text or numbers as a pattern of bars that a scanner reads. Unlike a QR code (2D), these are classic 1D barcodes used on products, labels, inventory, and shipping. Different symbologies suit different data — pick the one your scanner or system expects.
How it works here
Enter your data, choose a format, and the barcode renders instantly in your browser — nothing is uploaded. Download it as a PNG for screens or an SVG for print, which stays crisp at any size.
Which format to choose
Code 128 is the most flexible (any letters and numbers) — a good default. EAN-13 and UPC-A are for retail products and need a specific number of digits. Code 39 is common in industry and logistics. If a format shows an error, your data does not match its rules (for example, EAN-13 needs 12–13 digits).
Barcode vs QR code
A 1D barcode stores a short id (like a product number) and is read by laser scanners at checkout and in warehouses. A QR code stores much more (URLs, WiFi, contacts) and is read by phone cameras. Use a barcode for product/inventory ids, a QR code for links and rich data.
