About Barcode Generator
Create standards-aware barcodes with length and checksum validation and export SVG or PNG.
Barcode Generator validates CODE128, EAN-13, and UPC-A input and calculates or checks the required numeric checksum. Results can be downloaded as scalable SVG or raster PNG.
How to use it
- Enter or select your source data.
- Adjust the available options and run the tool.
- Review, copy, or download the result.
Common use cases
- Create sample labels for prototype packaging or UI tests.
- Verify a check digit before sending product data onward.
- Generate a scalable barcode graphic for internal mockups.
Worked example
Enter a 12-digit EAN payload and let the tool calculate its checksum.
Limitations and responsible use
- Generating a barcode does not register a retail identifier or grant ownership of a GTIN.
- Print size, quiet zones, contrast, substrate, and printer quality affect real scanner reliability.
- The tool covers only CODE128, EAN-13, and UPC-A.
Frequently asked questions
Can I invent an EAN or UPC for a product?
You can generate a technically valid test value, but commercial identifiers must come from the appropriate issuing authority.
Should I download SVG or PNG?
Use SVG for scalable print or design work and PNG when the destination requires a raster image.
