📖 How to Use Barcode & Product Label Generator (EAN-13, UPC)? (Step-by-Step Guide)

1

Step 1

Select your industry barcode symbology: EAN-13 (retail products), Code 128 (logistics & alphanumeric), UPC-A, or Code 39.

2

Step 2

Enter the numeric or alphanumeric code payload and customize bar width, height, and human-readable text visibility.

3

Step 3

Verify that the check digit and quiet-zone margins validate cleanly in the live vector preview.

4

Step 4

Download your print-ready barcode as a scalable SVG vector or high-resolution PNG image.

⚙️ GS1 / ISO 1D Symbology Encoding & Modulo-10 Checksum Verification

One-dimensional (1D) linear barcodes encode data through precise variations in parallel bar and space widths (modules) read by optical laser and CCD scanners. Even a 1-pixel rounding error or invalid check digit renders a printed production batch unreadable at retail checkout.

DH Tools implements exact ISO/IEC 15417 (Code 128) and ISO/IEC 15420 (EAN-13 / UPC-A) encoding tables in client-side JavaScript—generating mathematically exact vector SVG paths and high-DPI PNG labels with enforced quiet zones.

❓ Frequently Asked Questions

EAN-13 is the 13-digit GS1 standard used on global supermarket and retail merchandise (e.g. starting with 868/869 in Turkey). Code 128 is a high-density format used in warehouse logistics and internal inventory that encodes any ASCII letter or number.
The 13th digit is a Modulo-10 checksum computed from the first 12 digits. Our generator automatically calculates or validates the exact GS1 check digit so laser scanners never fail.
For professional offset printing in Adobe Illustrator or CorelDRAW, always download SVG so bars remain razor-sharp at any scale. For thermal label printers and Word/Excel sheets, high-res PNG works great.
Yes, all generated symbols strictly follow ISO/IEC 15420 (EAN/UPC) and ISO/IEC 15417 (Code 128) bar-to-space ratio tolerances.
