Frequently Asked Questions
Which barcode type should I choose?
Use Code 128 for general text and inventory IDs. Use EAN-13, EAN-8 or UPC-A only when your product number follows those retail standards.
Does this work without internet?
Yes. Once this HTML file is saved locally, barcode generation works without internet because it has no CDN or external library.
Can I print the barcode?
Yes. Use the Print button. For best scanning, keep strong contrast and avoid very small bar widths.
