Everything runs in your browser — nothing is uploaded.What a barcode is — and which type to pick
A barcode is just a machine-readable picture of a number or code. When a scanner reads it, your billing app looks that code up and pulls the right item, price and stock. The type you choose decides what characters and length the code can hold.
EAN-13
The 13-digit standard printed on most retail products worldwide. Digits only, fixed length — ideal when a product already carries a manufacturer barcode.
UPC-A
The 12-digit code common in North American retail. Like EAN-13 it is numeric and fixed-length — a check digit is calculated for you automatically.
Code 128 & Code 39
Flexible symbologies that hold letters and numbers of any length — perfect for your own internal SKUs or shelf codes. Code 128 is the compact, everyday default.
How to print your labels
- Type your product code and pick a barcode type — Code 128 works for almost any internal code.
- Choose a size and set how many labels you need, then check the preview sheet on the right.
- Download a PNG for a single label, or click Print labels and print the whole sheet onto sticker paper.
Put the labels to work at the counter
