Barcode Generator
Create standard barcodes like Code 128, Code 39, UPC, EAN, and more. All processing is done securely in your browser.
The Barcode Generator allows you to create widely-used 1D barcodes from your data. Barcodes are a machine-readable representation of data, commonly used in retail, logistics, and inventory management to quickly scan and track items. This tool generates barcodes entirely within your browser, ensuring your data remains completely private.
- Select Barcode Type: Choose your desired barcode format (e.g., Code 128, UPC).
- Enter Data: Type or paste the data you want to encode. Note that some formats have specific data requirements (e.g., UPC must be numbers).
- Generate: The barcode will be generated automatically as you type or change settings.
- Preview & Download: The barcode image will appear on the right, ready to be downloaded and used.
What are the different barcode types?
- Code 128: A versatile, high-density code that supports all ASCII characters. Excellent for logistics and inventory.
- Code 39: An older, widely-supported format that supports alphanumeric characters. Less dense than Code 128.
- EAN-13: The standard retail barcode in Europe and most of the world for consumer products. Requires 12 data digits (the 13th is a checksum).
- UPC-A: The standard retail barcode in the United States and Canada. Requires 11 data digits (the 12th is a checksum).
- ITF: (Interleaved 2 of 5) A numeric-only barcode often used for shipping and warehouse applications.
Can I create product barcodes (like on items at the store)?
Retail product barcodes (UPC/EAN) require a registered company prefix from GS1. While this tool can generate an image for a valid number, you cannot invent a number and use it on a commercial product. This tool is for general-purpose barcodes, not for creating official GS1-registered product codes.
Is my data secure?
Yes. All barcode generation is performed on your device. The data you enter is never sent to our servers.
