About Barcode Generator

AT USE Barcode Generator creates barcodes entirely in your browser — no data is uploaded to our servers. Choose from four widely used formats: Code 128 for general-purpose alphanumeric barcodes, EAN-13 for international retail product codes, UPC-A for US and Canadian retail items, and Code 39 for industrial and logistics labels. Every barcode downloads as an SVG (crisp at any print size) or PNG (ready for web and screen use).

Common use cases

  • Create a Code 128 barcode for an inventory label or internal tracking system.
  • Generate a test EAN-13 barcode to verify scanner setup before printing production labels.
  • Produce a UPC-A barcode for a product prototype and check it scans correctly in-store.
  • Add Code 39 barcodes to asset tags, file folders, or event wristbands.
  • Export high-resolution SVG barcodes for embedding in InDesign, Illustrator, or PDF templates.

How to generate a barcode

  1. Select a barcode format from the dropdown.
  2. Type your data in the input field (EAN-13: 12 digits; UPC-A: 11 digits; Code 128/39: text).
  3. The barcode preview updates live as you type.
  4. Click Download SVG for a scalable vector file, or Download PNG for a raster image.

Frequently asked questions

Is this barcode generator free?

Yes — completely free. No account required, no watermarks, no usage limits.

What barcode formats are supported?

Code 128 (most versatile — letters, numbers, and symbols), EAN-13 (13-digit international retail), UPC-A (12-digit US/Canadian retail), and Code 39 (alphanumeric, widely used in logistics and industrial settings).

What is the difference between EAN-13 and UPC-A?

EAN-13 is the international barcode standard used on retail products worldwide. UPC-A is a 12-digit format used primarily in the US and Canada. A UPC-A barcode is equivalent to an EAN-13 with a leading zero, so the same scanner reads both.

How many digits does an EAN-13 barcode need?

Enter exactly 12 digits. The 13th digit is a check digit calculated automatically and added to the barcode. If you enter a full 13-digit EAN, the tool validates the check digit.

Can I download the barcode as an SVG?

Yes. SVG is a scalable vector format that stays sharp at any size — ideal for product labels, packaging artwork, and print-ready files. PNG is also available for web and digital use.
