What This Tool Does
The Barcode Generator creates standard barcodes in Code 128, EAN-13, and UPC-A formats. Enter your value, preview the barcode instantly, and download it as a PNG or SVG file ready for printing or digital use.
Barcodes are used in retail, warehousing, logistics, and inventory management to encode product identifiers, tracking numbers, and other data in a machine-readable format. This tool validates your input against each format's requirements and generates accurate, scannable barcodes.
Common Use Cases
- Creating product labels with EAN-13 or UPC-A barcodes for retail packaging.
- Generating Code 128 barcodes for internal inventory tracking and warehouse management.
- Printing barcode labels for shipping boxes and logistics tracking.
- Creating asset tags for office equipment, tools, or library items.
- Generating barcodes for event tickets or membership cards.
- Producing barcode stickers for small business product labeling.
How to Use This Tool
- Select the barcode format: Code 128 (any text), EAN-13 (12-13 digits), or UPC-A (11-12 digits).
- Enter the value you want to encode in the input field.
- The tool validates your input and shows any format-specific errors.
- Preview the barcode in real time once the input is valid.
- Download the barcode as PNG (for screen use) or SVG (for high-quality printing).
Best Practices and Tips
- Choose the correct format for your use case: EAN-13 for international retail products, UPC-A for North American retail, and Code 128 for general-purpose encoding.
- Double-check your input digits before generating — an incorrect barcode can cause scanning failures at point of sale.
- Download SVG format for print applications. SVG scales to any size without losing quality.
- Leave adequate quiet zones (blank space) around the barcode when incorporating it into labels or packaging.
- Test printed barcodes with a scanner before committing to a full print run.
- For EAN-13 and UPC-A, the check digit is calculated automatically if you enter 12 or 11 digits respectively.
