Frequently Asked Questions About Our Free Barcode Generator

Common questions about generating barcodes, formats, and usage.

What is a barcode generator?

Down Arrow
A barcode generator is an online tool that creates visual barcode images from your text or numbers. These barcodes can be scanned by barcode readers to quickly identify products, track inventory, or look up information. Our free barcode generator creates standard barcode formats used in retail, logistics, and various industries.

How do I use this free barcode generator?

Down Arrow
Using this barcode generator is simple. First, select your barcode type from the dropdown menu. Then enter your data such as a product code or serial number. The barcode appears instantly in the preview area. You can customize the appearance using the sliders. Finally, download your barcode as PNG or SVG, or copy it to your clipboard.

What barcode formats does this tool support?

Down Arrow
This free barcode generator supports eight popular formats: Code 128 for general purpose use, EAN-13 for European retail products, UPC-A for North American retail, Code 39 for industrial applications, ITF-14 for shipping containers, Codabar for libraries and blood banks, MSI for inventory control, and Pharmacode for pharmaceutical packaging.

Is this barcode generator really free?

Down Arrow
Yes, this barcode generator is completely free with no hidden costs. There are no premium tiers, no usage limits, and no signup required. You can generate as many barcodes as you need for personal or commercial use. We offer this tool as a service to help small businesses create professional barcodes.

Do I need to sign up or create an account?

Down Arrow
No signup or registration is needed. Just visit this page and start generating barcodes immediately. We do not ask for your email, name, or any personal information. The tool is ready to use the moment you open the page.

Can I use these barcodes for commercial products?

Down Arrow
Yes, you can use the barcodes generated by this tool for commercial products. However, for retail products, you typically need to register with GS1 to get a unique company prefix for EAN and UPC barcodes. The barcode generator creates the visual representation, but the numbers must be properly registered for official use.

What is the difference between Code 128 and EAN-13?

Down Arrow
Code 128 is a versatile format that can encode any text and numbers, making it ideal for internal use, shipping labels, and general purpose barcoding. EAN-13 is a standardized format specifically for retail products, containing 13 digits that identify the country, manufacturer, and product. EAN-13 is used for products sold internationally.

How do I print the generated barcode?

Down Arrow
Download your barcode as PNG or SVG for regular printers, or use PRN format for thermal label printers. PRN files contain ZPL commands that work directly with Zebra and compatible printers. Simply send the PRN file to your thermal printer to print barcode labels instantly.

Is my data secure when using this barcode generator?

Down Arrow
Your data is completely secure. All barcode generation happens locally in your web browser using JavaScript. Your product codes, serial numbers, and other information never leave your device. Nothing is uploaded to any server, stored, or tracked. Close the browser and everything is gone.

Can I generate barcodes in bulk?

Down Arrow
This tool is designed for generating individual barcodes. For bulk barcode generation with hundreds or thousands of products, consider using Zubizi ERP which includes built-in barcode generation for your entire product catalog, along with barcode printing and inventory management features.

What size should my barcode be for product labels?

Down Arrow
For most retail product labels, a barcode width of 1 to 2 inches is standard. Use the customization sliders to adjust bar width and height. For EAN-13 and UPC barcodes, maintain the recommended proportions for reliable scanning. Download as SVG if you need to resize later without losing quality.

Does this barcode generator support thermal label printers?

Down Arrow
Yes, this is one of the few free barcode generators that supports thermal printers directly. Download your barcode as a PRN file which contains ZPL commands compatible with Zebra and other thermal label printers. Just send the file to your printer for instant barcode labels.

Why should I use this barcode generator instead of others?

Down Arrow
This barcode generator offers unique features most others do not. Live preview updates as you type, PRN export for thermal printers, and complete privacy with no data uploads. Built by Zubizi, retail software specialists, it has no watermarks, no limits, and no ads.
