UPC Generator

About

UPC Generator creates retail-grade barcodes — UPC-A, UPC-E, FNSKU,
and Code128 — directly from your browser toolbar. No account
required, no sign-up, no ads.

What you can do
• Pick a symbology, type the value, get a clean barcode preview in
  one click.
• Built-in validation that mirrors each spec — check digit, length,
  alphabet.
• Auto-fix mode that completes the check digit for you while you type.
• Copy the barcode to clipboard as PNG, or download as SVG/PNG for
  print, design tools, or inventory systems.
• Print a ready-to-use label sheet sized for thermal label printers.
• Local history of recently generated barcodes — stays on your device.
• Customizable appearance: bar width, height, quiet zone, font.

Built for
• Amazon FBA sellers preparing FNSKU labels for inbound shipments.
• Small retail teams adding UPC-A or UPC-E tags to inventory.
• Warehouse and logistics teams printing Code128 SKU labels.
• Anyone who needs a fast, no-friction barcode tool in the browser.

Privacy
The extension contacts only the project's backend API to render the
barcode image. No analytics. No trackers. No third-party data sharing.
Local history never leaves your device. Full policy linked below.
