What These Barcode Tools Do
This page gives you a set of free, browser-based barcode tools built for product sellers, Amazon FBA operators, and anyone working with UPC, EAN, or GTIN codes. Every tool runs instantly in your browser — no software to download, no account to create.
- Barcode Generator — Generate UPC-A, EAN-13, EAN-8, and Code 128 barcodes in bulk. Output as PNG or SVG, ready for labels or artwork files. Useful for previewing and working with barcodes you already own.
- FNSKU Label Generator — Create print-ready FNSKU barcode labels for Amazon FBA shipments. Supports Avery 5160 format and batch output so you can cover an entire inventory run at once.
- Barcode Converters — Convert between UPC-A and UPC-E formats, or look up Amazon ASINs from UPC codes. Useful when marketplaces require a specific format or when you need to cross-reference product data across platforms.
- Barcode Quantity Calculator — Enter your products and variations (size, color, flavor, etc.) and get an exact barcode count before you buy. Each variation requires a unique code, and this tool makes sure you do not under-order.
- Label Tools — Generate country of origin labels, product stickers, and shipping labels. Includes compliance-friendly formats for retail and e-commerce products across multiple markets.
- SKU Generator — Build a consistent internal SKU system for your inventory with customizable naming formats and CSV export.
- QR Code Tools — Generate custom QR codes for links, plain text, WiFi credentials, and contact cards, or scan and decode existing QR codes right in your browser. Codes are static, never expire, and carry no watermark.
If you need actual UPC or EAN barcodes to list products on Amazon or in retail stores, you can purchase barcodes directly — these tools are separate from the barcodes themselves.

Privacy & How the Tools Work
Every tool on this page runs entirely inside your browser. When you enter a barcode number, product name, FNSKU code, or any other data, that information is processed locally on your device and is never sent to our servers.
There is no login, no session tracking tied to your inputs, and no data stored between visits. You can use these tools as often as you need without creating an account or sharing anything about your business.
The tools load quickly and work on any modern browser — desktop or mobile. For label printing, a desktop or laptop with a connected printer will give you the most reliable output, particularly for Avery-format FNSKU sheets.

Barcode Tools: Common Questions Answered
Are these barcode tools really free to use?
Yes. Every tool on this page is completely free. There is no account required, no trial period, and no hidden cost. The tools are browser-based and available to use as often as you need. If you need actual UPC or EAN barcodes to sell products, those are available separately through our barcode packages.
Do the tools store or share any of my data?
No. All of our free barcode tools run entirely in your browser. Nothing you enter — product names, SKUs, barcode numbers, or label data — is sent to a server or stored anywhere. Your information stays on your device throughout the entire session.
Which barcode formats do these tools support?
Our barcode generator and converter tools support the most common retail and e-commerce formats, including UPC-A, UPC-E, EAN-13, EAN-8, Code 128, QR Code, and FNSKU (used by Amazon FBA). UPC is standard for the US and Canada; EAN-13 is used across Europe and most international markets.
What is the difference between UPC, EAN, GTIN, and FNSKU?
UPC (12 digits) and EAN (13 digits) are retail barcodes used to identify products at point of sale. GTIN is the umbrella term that covers both — a UPC-A is a 12-digit GTIN, and an EAN-13 is a 13-digit GTIN. FNSKU is different: it is an Amazon-specific identifier used to track your inventory inside FBA warehouses. Most sellers need a UPC or EAN to create an Amazon listing, and Amazon then assigns an FNSKU to their inventory.
How can Amazon sellers use these tools?
Amazon sellers can use this page to calculate how many barcodes they need across product variations, generate printable FNSKU labels in Avery 5160 format for FBA shipments, look up ASINs from UPC codes, and convert between UPC-A and UPC-E formats. Learn more about how Amazon handles barcodes on our Amazon barcode guide.
Can I use the barcode generator to create barcodes I can actually sell with?
The bulk barcode generator is designed for previewing, testing, and working with barcodes you already own. If you need UPC or EAN barcodes to sell products on Amazon, retail stores, or online marketplaces, those need to be legitimately sourced. You can purchase barcodes from BarCodesTalk with instant delivery and no annual fees.
How do I know how many barcodes I need?
Each unique product variation — including differences in size, color, flavor, or style — requires its own unique barcode. A t-shirt sold in three colors and four sizes would need 12 separate barcodes. Use the Barcode Quantity Calculator on this page to enter your products and variations and get an accurate count before you buy.
Can I create and scan QR codes for free?
Yes. The QR Code Generator lets you create custom QR codes for links, plain text, WiFi credentials, and contact cards. The codes are static, never expire, and carry no watermark, and can be downloaded as PNG or SVG for print. The QR Code Scanner decodes existing QR codes using your device camera or an uploaded image. Both tools run entirely in your browser and are completely free.
Do these tools work on mobile devices?
Yes. The tools are browser-based and work on any modern device including phones and tablets. The barcode scanner tool can access your device camera directly to scan and decode UPC, EAN, and QR codes in real time. For label printing, a desktop or laptop is recommended for the most reliable results.
