UPC Generator

UPC-A, UPC-E, FNSKU and Code128 barcode generator. Validate, copy, download SVG/PNG, or print a label sheet from the toolbar.

UPC Generator is a free Chrome extension that creates retail-grade UPC-A, UPC-E, FNSKU, and Code128 barcodes directly from your browser toolbar. Type a value, click once, get a clean, scannable barcode — no account, no sign-up, no ads. Why UPC Generator instead of an online tool Most online UPC generators ask you to leave the page you are working on, sign up, sit through ads, or trust your data to an unknown server. UPC Generator lives in your Chrome toolbar, so the barcode you need is one click away from Amazon Seller Central, a Shopify dashboard, a Google Sheets inventory list, or a packing-slip PDF. The popup opens instantly and remembers your last symbology, so repeat work takes seconds. What UPC Generator can do • Generate UPC-A and UPC-E retail barcodes for product listings on Amazon, eBay, Walmart, Shopify, and other marketplaces. • Create FNSKU labels for Amazon FBA inbound shipments in the exact format Amazon expects from its stickering service. • Generate Code128 barcodes for internal SKUs, warehouse bins, and logistics labels. Built-in validation and Auto-fix UPC Generator checks every barcode against its official specification before rendering — check-digit math, length, and allowed character set. If your input is missing the final check digit, Auto-fix mode completes it while you type, so you cannot accidentally print or send an invalid label. Errors are explained in plain English, not cryptic codes. Export options that fit real workflows • Copy to clipboard as PNG — paste straight into your design tool, document, or chat. • Download as SVG — scale to any size with zero quality loss, perfect for vector workflows and print. • Download as PNG — drop into product listings, packaging mockups, or shipment paperwork. • Print a label sheet — pre-sized for standard thermal label printers. Generate a full sheet of barcodes in one click. Local history and customization Recently generated barcodes are saved on your device for instant re-print. The history list is stored in chrome.storage and never synced to a server. Appearance is fully tunable: bar width, height, quiet zone, font size, and label position — match the spec of any printer or marketplace. 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. • E-commerce operators who need a fast, no-friction UPC generator in the browser. Privacy first UPC Generator contacts only the project's backend API to render the barcode image. No analytics, no trackers, no third-party data sharing. Your local history stays on your device. The full privacy policy is linked from the developer's website. Honest about what it does UPC Generator is open about what it does and what it doesn't do. No hidden permissions, no remote code, no surprise behavior. Install once, generate retail and FBA barcodes whenever you need them.
