How it works
Generate practical Code 128, EAN-13, and UPC-A barcodes with local SVG and PNG export.
Use it to create a standards-aware barcode graphic for a known identifier.
Example
Generate an EAN-13 symbol from a valid 12- or 13-digit product number.
Notes
- Code 128 uses printable ASCII in this first version.
- EAN-13 and UPC-A accept values with or without the final check digit.
- Exports are generated locally from the rendered SVG.
Constraints
- EAN-13 and UPC-A require valid numeric lengths; Code 128 supports practical text.
- Limit: Format-specific barcode length. Nothing is uploaded or silently truncated.
Common errors
- Wrong numeric length
- Invalid check digit
- Unsupported Code 128 character
When to use it
Use it to create a standards-aware barcode graphic for a known identifier.
Formats: Code 128, EAN-13, UPC-A, SVG, PNG.
