Everything you need to know about barcodes
What is a barcode?
A barcode encodes data — almost always a numeric product code — as a pattern of parallel lines of varying widths, readable by a laser or camera scanner. Unlike a QR code, a traditional barcode is one-dimensional and holds relatively little data, which is exactly enough for its main job: identifying a product.
When you actually need this
- Labeling products for retail with a standard EAN-13 or UPC code.
- Internal inventory tracking using Code 128 or another format your warehouse system reads.
Barcode vs. QR code
A barcode holds a small amount of data (typically just a product number) in one dimension; a QR code holds dramatically more data (a full URL, WiFi credentials, a contact card) in two dimensions. Use a barcode specifically when you need a standard retail/inventory format like EAN-13, UPC, or Code 128 — use QR Code Generator for anything else.

Frequently Asked Questions
Which barcode format should I use?
EAN-13 and UPC are standard for retail products; Code 128 is more flexible and commonly used for internal inventory or shipping labels. Check what your scanner or retailer requires before picking one.
Do EAN-13 and UPC codes need to be officially registered?
For retail sale, yes — EAN/UPC prefixes are issued by GS1. This tool generates a valid barcode image from any number you provide, but doesn't register or issue new product codes.
What's the difference between the PNG and SVG download?
PNG is a fixed-resolution image suitable for screens and most printing; SVG is a vector file that scales to any size — useful for large-format labels — with no quality loss.
Will the barcode still scan if printed small?
Scannability depends on print resolution and the scanner used — test a sample print at your intended size before running a full batch.
What's the difference between a barcode and a QR code?
A barcode encodes data in a single line and holds relatively little, usually just a product number. A QR code encodes data in two dimensions and can hold dramatically more, like a full URL or contact card.
Is this tool free to use?
Yes — completely free, with no signup and no watermark on the output.
