Generate Barcodes Online —
Quickly and Simply

You can generate barcodes for free and use them for
both personal and commercial purposes
1. Choose a barcode type

Select one of the five supported formats:

  • EAN‑13
  • EAN‑8
  • Code 128
  • UPC
  • Data Matrix

If you’re unsure which format to choose, start with Code 128 — it’s universal, widely supported, and works with nearly all barcode scanners.

2. Enter your data

In the Barcode data field, enter the characters that will be encoded:

  • Add your data line by line — each line becomes a separate barcode.
  • Need several identical barcodes? Duplicate the line as many times as required.
  • Need different barcodes? Enter different values.

This is the fastest way to create multiple barcodes in bulk using the online barcode generator.

3. Adjust barcode settings

Customize the appearance of your barcode:

  • Set width and height
  • Show or hide barcode numbers
  • Choose text size: large, medium, or small

All elements — bars, spacing, and numbers — automatically adapt to the selected dimensions.

4. Preview the generated barcode

The preview updates instantly as you modify your settings, so you can fine‑tune the barcode before exporting it.

5. Choose an export format

Download your barcode in one of the available formats:

  • PNG
  • JPEG
  • SVG

SVG is ideal if you need a scalable, print‑ready barcode.

6. Download your barcode

Click Download to save the generated barcode. You can print it, add it to product labels, or upload it to your inventory system.

How You Can Benefit from the Calculator

EAN‑13

EAN‑13 is the global standard for retail product marking. It is widely used in supermarkets, consumer goods, and international trade. Most GS1‑registered products worldwide rely on this format because it’s easy to scan and supports automated checkout systems.

Typical use cases:

EAN‑8

EAN‑8 is a compact version of the EAN standard. It is used when packaging space is limited and the full EAN‑13 code doesn’t fit the design. Despite its smaller size, it still provides fast and reliable scanning.

Typical use cases:

  • Small packages
  • Cosmetics, snacks, compact retail goods
  • Products with limited label space

Code 128

Code 128 is a versatile, high‑density barcode widely used in logistics, warehousing, and internal business operations. It supports numbers, letters, and special characters — ideal for encoding structured data like SKUs, batch numbers, and internal identifiers.

Typical use cases:

Data Matrix

Data Matrix is a 2D barcode that stores large volumes of information in a compact space. It is exceptionally durable and can be scanned even when partially damaged, making it popular in manufacturing, electronics, and healthcare.

Typical use cases:

  • Serial numbers on components
  • Medical and pharmaceutical marking
  • Small industrial parts where space is limited

UPC

UPC (Universal Product Code) is the dominant retail barcode format in the United States and Canada. It is used for point‑of‑sale scanning, product identification, and stock management.

What Is a Barcode?

A barcode is a machine-readable code that stores product or item information using a sequence of lines, spaces, or geometric patterns.

Barcodes help automate product identification, speed up checkout, track inventory, and reduce manual errors.

They are widely used in retail, ecommerce, logistics, manufacturing, and warehouse operations.

Most businesses rely on standard barcode formats such as EAN‑13, UPC, Code 128, EAN‑8, and Data Matrix, all of which you can generate using our free online barcode generator.
