How to use

How to use Barcode Generator

  1. 01

    Enter your barcode data

    Type a single value, or flip on Bulk mode to paste many codes at once — one per line. You can also import a CSV and the first column becomes your barcode list automatically.

  2. 02

    Choose a format

    Pick the symbology that matches your use case: EAN-13 or UPC-A for retail products, CODE128 for shipping and internal SKUs, ITF-14 for cartons, or CODE39, MSI, Codabar, and Pharmacode for specialized systems. Invalid values are flagged instantly.

  3. 03

    Style and size it

    Adjust bar width and height, toggle the human-readable text, and set custom bar and background colors. Enable Thermal mode for 4×6 label printers.

  4. 04

    Export or print

    Download any barcode as a vector SVG or high-resolution PNG, export the whole batch as a multi-up PDF, or send everything straight to your printer.

Overview

Generate barcodes for products and inventory

Create scannable barcodes in common formats for retail, warehousing, labeling, and asset tracking. Enter your value, pick a format, and download a crisp image ready to print — no account or software installation required.

Reliable codes that actually scan

A barcode is only useful if scanners read it the first time, so the generator outputs clean, standards-compliant images at print quality. Use it to label inventory, build product SKUs, or prototype a labeling system before investing in dedicated hardware.

FAQ

Frequently asked questions

How do I generate a barcode for my product for free?+

Select your barcode type (EAN-13 for retail products, CODE128 for general use), enter your barcode number, adjust width and height, then click Generate. Download as SVG or PNG.

What barcode format should I use for retail products?+

EAN-13 is the global standard for retail products sold internationally. UPC-A is used mainly in North America. CODE128 is versatile for internal use, shipping, and logistics.

Why should I use SVG format for barcodes?+

SVG is a vector format — it scales to any size without losing quality. A barcode on a tiny label will scan just as well as one on a large banner. PNG barcodes can become blurry when enlarged for large-format printing.

Can I generate barcodes for Amazon FBA?+

Yes. Amazon FBA requires FNSKU barcodes (CODE128 format). Enter your FNSKU code, generate in CODE128 format, download at high resolution, and print labels at 1x2 inch size.

Does my barcode data get stored anywhere?+

No. Barcode generation runs entirely in your browser. Your product codes and data never leave your device.

How do I print barcodes at the correct size for labels?+

Download as SVG (vector) for print — it scales to any size without pixelation. For standard retail shelf labels, print at 1.5" wide × 1" tall minimum. For shipping labels, 2"×1" or 4"×2" are common sizes. Set your printer to 300 DPI or higher for crisp, scannable bars.

Which barcode format should I use for retail?+

EAN-13 is standard for retail products worldwide; UPC-A is common in North America. CODE128 suits internal inventory and shipping labels.

Why export as SVG?+

SVG is vector, so barcodes stay razor-sharp at any print size — important for reliable scanning.
