Use Cases

EAN-13 Barcode Generator for Retail Products

EAN-13 is the global retail standard used on virtually every product sold outside North America. Enter your 12-digit product code and the tool appends the correct check digit automatically. Download the SVG for use in print artwork or product packaging templates.

Code 128 Barcode Generator for Shipping and Logistics

Code 128 supports all 128 ASCII characters with no length restriction, making it the format of choice for shipping labels, inventory tags, and warehouse management systems. Alphanumeric SKUs, order numbers, and serial codes all encode cleanly.

UPC-A Barcode Generator for North American Retail

UPC-A is the standard for retail products sold in the United States and Canada. Enter 11 data digits and the 12th check digit is calculated instantly. Download PNG or SVG to include in point-of-sale system setups or product packaging.

Free Barcode Maker for Small Businesses

Small businesses and independent sellers can generate compliant barcodes for inventory management, price tags, and marketplace listings without paying for expensive dedicated software. All formats render correctly and are suitable for label printers and scanners. To keep packaging files lean, compress the exported PNG before embedding it in design templates, and use the URL encoder to safely encode product page links for any accompanying print materials.

FAQ's

Enter exactly 12 digits — the 13th check digit is calculated and appended automatically. EAN-13 barcodes always contain 13 digits total. This format is used on virtually every retail product sold outside North America.
Yes. Code 128 supports all 128 ASCII characters including uppercase and lowercase letters, digits, spaces, and most punctuation marks. It is the most versatile linear barcode format, widely used in e-commerce shipping labels and inventory systems.
PNG is a raster image generated from the SVG at the current display size — suitable for standard printing and digital use. SVG is a lossless vector format that scales to any size without pixelation, making it the preferred choice for professional print production and large-format labels.
Check that your value meets the format requirements (e.g. exactly 12 digits for EAN-13). Print at sufficient size — EAN-13 should be at least 25mm wide. Ensure strong contrast between the bar color and background. Avoid light bars on dark backgrounds, which most scanners struggle with.
No. All barcode generation runs entirely in your browser using JavaScript. Your product codes and data never leave your device. The tool also works offline once the page has loaded.
Code 39 supports uppercase letters A–Z, digits 0–9, and the special characters: hyphen (-), period (.), space, dollar sign ($), slash (/), plus (+), and percent (%). Lowercase letters are automatically converted to uppercase by the validator.
For EAN-13, EAN-8, and UPC-A the tool uses a weighted modulo-10 algorithm. Odd-position digits are multiplied by 1, even-position digits by 3, and the results are summed. The check digit is (10 − (sum mod 10)) mod 10. The calculated digit is shown below the input and appended before rendering.
