Free Barcode Generator – Create UPC, EAN-13 & Code 128

Yes. Our barcode generator is 100% free with no paywalls, registration, or commercial licensing fees. You can generate and print barcodes for retail consumer products, warehouse cartons, and business operations without restrictions.

EAN-13 (International Article Number) is the global retail standard consisting of 12 data digits plus 1 check digit (total 13 digits). UPC-A (Universal Product Code) is the United States and Canadian standard with 11 data digits plus 1 check digit (total 12 digits). UPC-A is technically a subset of EAN-13 (with a leading zero).

For EAN-13, EAN-8, UPC-A, and ITF-14 standards, the generator employs a modulo-10 weighted sum algorithm (alternating weights of 1 and 3). You only need to type the data digits, and the mathematical check digit is automatically computed and appended.

Code 128 is the industry benchmark for shipping labels, logistics waybills, and warehouse bin tracking due to its high data density and support for the full 128-character ASCII table. For corrugated master shipping cartons, ITF-14 is the standard format.

Yes. Switch to the 'Batch / Avery Sheet' tab, paste up to 200 barcode values (one per line), select your desired Avery template (such as L7163, L7160, or 5160), and download a ready-to-print multi-page PDF.

You can export individual barcodes in scalable vector SVG (ideal for packaging artwork in Illustrator), high-resolution 300 DPI raster PNG (for digital documents and desktop printing), or standalone sized PDF format.

No. All barcode generation, canvas rasterization, and PDF sheet compilation take place 100% locally inside your web browser. No product numbers, pricing, or internal serials are ever uploaded to any cloud server.

Scanning failures are commonly caused by three factors: lack of a white quiet zone margin on either side of the barcode, low contrast between bars and background, or incorrect printer scaling when printing Avery sheets. Always print at 100% scale.

Code 39 is an alphanumeric symbology encoding uppercase letters (A–Z), digits (0–9), and 7 special characters. It is widely used in US Department of Defense logistics, automotive manufacturing, and industrial inventory systems.

Yes. In the Advanced settings panel, you can enter custom label text to override the bottom digits with product names, SKU descriptions, or price tags, or toggle human-readable text off completely.

Yes. High-resolution PNG and vector SVG exports can be loaded into thermal label printing software (like Zebra Designer, Brother P-touch, or Dymo Label) to print directly onto thermal rolls.

For official international retail store distribution (like selling products in Walmart, Target, or supermarkets), you must license an official GS1 company prefix. For internal inventory, warehouse bin tags, or asset tracking, you can generate any custom numeric sequence freely.

Yes. The interface is fully responsive on smartphones, tablets, laptops, and desktop computers across iOS, Android, macOS, and Windows.

Yes. Click the 'Copy SVG' button to copy the raw SVG XML code directly to your clipboard for instant pasting into Figma, Adobe XD, or web HTML editors.
