About Barcode Generator
A barcode generator is an indispensable tool for businesses, retailers, warehouse managers, and anyone who needs to label products, assets, or inventory with scannable barcodes. Our free barcode generator online lets you create professional-grade barcodes in six popular formats — Code 128, Code 39, EAN-13, UPC-A, ITF, and CODABAR — all from your web browser without installing any software. Whether you're a small business owner adding barcodes to product packaging, a librarian cataloging books, a logistics coordinator tracking shipments, or a student learning about supply chain systems, this tool makes barcode creation instant, free, and hassle-free.
The tool supports a wide range of barcode symbologies for different use cases. Code 128 is the most versatile, encoding alphanumeric data with high density — perfect for shipping and supply chain labels. Code 39 is a widely used standard in non-retail environments like government and healthcare. EAN-13 and UPC-A are the global standards for retail product identification, scanned at point-of-sale systems worldwide. ITF (Interleaved 2 of 5) is commonly used in warehouse and distribution environments for outer carton labeling. CODABAR is used in blood banks, libraries, and air parcel shipping. Each format has specific data requirements, and our tool provides real-time guidance on what type of input each barcode expects.
Our online barcode maker processes everything instantly on the server side and returns a high-resolution PNG image that you can download with a single click. The barcode is rendered with sharp, clean lines suitable for both digital use and professional printing. You can customize the width and height of the barcode image — width from 50 to 1000 pixels and height from 20 to 500 pixels — giving you full control over the dimensions for labels, stickers, product tags, invoices, and more. There are no watermarks, no ads overlaid on your downloaded image, and no restrictions on commercial use.
Privacy and security are central to the experience. Your data — whether it's product codes, serial numbers, or internal identifiers — is transmitted securely over HTTPS and processed in real time. We do not store, log, or retain any data you enter. Once you close the page or refresh, the information is permanently gone. This means you can confidently generate barcodes for proprietary product numbers or sensitive internal codes without worrying about data breaches or information leakage.
From retail entrepreneurs and e-commerce sellers to logistics managers, healthcare administrators, and educators — anyone who needs to create barcodes quickly and reliably will benefit from this free barcode generator. It works on all modern browsers including Chrome, Firefox, Safari, and Edge, and is fully responsive on mobile devices. There is no software to download, no account to create, and no learning curve. Simply open the page, select your barcode type, enter your data, and download your barcode in seconds.
How to Generate a Barcode Online
Creating a barcode with our online generator takes just a few simple steps:
- Select barcode type: Choose from Code 128, Code 39, EAN-13, UPC-A, ITF, or CODABAR from the dropdown menu. Each type has specific data format requirements — the help text below the data input field will guide you.
- Enter your data: Type or paste the information you want to encode. Make sure the data matches the selected barcode format. For example, EAN-13 requires exactly 12 digits, UPC-A requires 11 digits, and ITF requires an even number of numeric digits. Code 128 and Code 39 are more flexible and accept alphanumeric input.
- Adjust dimensions (optional): Set the barcode width (50–1000 pixels) and height (20–500 pixels) to suit your intended use. For product labels and stickers, 200x80 pixels is a good starting point. For shipping labels, consider 400x120 pixels or larger.
- Click "GENERATE BARCODE": The tool will instantly process your request and display the barcode in the preview panel on the right. A loading spinner will appear briefly.
- Preview and download: Once generated, you'll see the barcode in the preview area. Click the green "Download Barcode" button to save it as a PNG image. Test the barcode with a scanner before printing commercially.
Tip: Always validate your barcode data format before generating. EAN-13 must be 12 digits, UPC-A must be 11 digits, and ITF requires an even number of digits. For Code 128 and Code 39, avoid special characters unless supported. Test printed barcodes with a barcode scanner before mass production.
Frequently Asked Questions
A barcode generator is an online tool that converts text or numeric data into a machine-readable barcode image. These barcodes can be scanned by barcode readers, smartphones, and point-of-sale systems to instantly retrieve the encoded information such as product IDs, serial numbers, or tracking codes.
Yes, it is completely free with no hidden charges, subscription fees, or credit card requirements. You can generate unlimited barcodes for personal and commercial use. The downloaded PNG images have no watermarks, and there are no usage caps or restrictions.
No registration or account creation is required. You can start generating barcodes immediately without signing up, logging in, or providing any personal information. The tool is designed for instant, anonymous use.
Absolutely. Your data is transmitted over a secure HTTPS connection and processed in real time. We do not store, log, or retain any data you enter — including product codes, serial numbers, or any other information. Once you close the page, your data is permanently gone.
We support six barcode symbologies: Code 128 (alphanumeric, high density), Code 39 (alphanumeric, widely used in non-retail), EAN-13 (12-digit retail product code), UPC-A (11-digit retail code for North America), ITF (numeric, even digits, for outer cartons), and CODABAR (numeric with some symbols, used in libraries and blood banks).
The barcode is downloaded as a high-quality PNG image file. PNG is a lossless raster format that preserves the sharp edges and fine lines of barcodes, making it suitable for both digital display and professional printing on labels, stickers, and packaging.
You can customize the barcode width from 50 to 1000 pixels and height from 20 to 500 pixels. Smaller sizes (150–250px wide) are suitable for small product labels and tags. Larger sizes (400–800px wide) work well for shipping labels, warehouse bin labels, and signage.
No, there is no limit. You can generate as many barcodes as you need, as many times as you want. Use the tool for all your projects — personal inventory, product labeling, or commercial applications — without any restrictions.
Yes, barcodes generated with this tool can be used for both personal and commercial projects without any restrictions. There are no licenses, attribution requirements, or usage limitations. However, for retail barcodes (EAN-13, UPC-A), you must obtain a valid GS1 company prefix to ensure your barcodes are globally unique and compliant.
The tool works on all modern browsers including Google Chrome, Mozilla Firefox, Apple Safari, Microsoft Edge, and Opera. It also works on mobile browsers on both iOS and Android devices.
Absolutely. The page is fully responsive and works seamlessly on smartphones and tablets. You can generate and download barcodes directly from your mobile browser, making it convenient to create barcodes on the go in warehouses, retail stores, or during site visits.
If your barcode isn't scanning, check these common issues: ensure the data format matches the barcode type requirements (e.g., EAN-13 needs 12 digits), verify the barcode has enough contrast between bars and background, make sure the image resolution is high enough for the printing size, and confirm the barcode isn't distorted or stretched during scaling. For printed barcodes, ensure the print quality is sharp and the barcode isn't smudged.
Barcode generation is nearly instant — typically under one second. The processing happens on our server and the result is displayed immediately in the preview panel. Downloading the PNG file is also instant.
No, the barcodes generated by this tool do not expire. The PNG image is static and remains scannable indefinitely as long as the image quality is preserved. However, if the data encoded in the barcode becomes outdated (e.g., a product code changes), you will need to generate a new barcode with the updated information.
No, barcodes are static images and cannot be edited after generation. If you need to change the encoded data, you must create a new barcode with the updated information. Always double-check your data before downloading.
EAN-13 (European Article Number) is a 13-digit barcode used internationally for retail products. UPC-A (Universal Product Code) is an 11-digit barcode used primarily in the United States and Canada. The main difference is the number of digits and the regional usage. Both formats encode a product identifier that is scanned at point-of-sale terminals. Our tool automatically computes the check digit for both formats.
For internal use such as inventory management, asset tracking, or warehouse labeling, you can use any barcode format without a license. However, if you intend to sell products in retail stores that require EAN-13 or UPC-A barcodes, you must obtain a valid GS1 company prefix and assign unique product numbers to ensure your barcodes are globally compliant and do not conflict with other products.
Currently, our tool generates the barcode image without human-readable text below it. The PNG file contains only the barcode pattern. If you need to add text such as product names or prices below the barcode, you can edit the downloaded PNG in any image editing software before printing.
Barcode Generator – Free Online Tool for Fast and Easy Results
Introduction
In the modern world of retail, logistics, and inventory management, barcodes are everywhere. They speed up checkout at supermarkets, track packages across continents, organize warehouse stock, and ensure accuracy in healthcare and manufacturing. But if you need to create a barcode for a product, asset tag, or label, you might think you need expensive software, specialized fonts, or a GS1 subscription just to get started. That's simply not true anymore. Our free barcode generator online lets you generate barcodes in multiple industry-standard formats directly from your browser — no installation, no cost, and no complexity. Whether you're launching a new product line, organizing a home inventory, or building a school project, this tool makes professional barcode creation accessible to everyone.
What Is a Barcode Generator?
A barcode generator is a tool that encodes text or numeric data into a visual pattern of parallel lines (bars) and spaces that can be read by optical scanners. Different barcode symbologies exist for different purposes — some encode only numbers, others encode letters and symbols, and each has specific rules about data length and format. Our online barcode maker supports six of the most widely used barcode types: Code 128, Code 39, EAN-13, UPC-A, ITF, and CODABAR. You simply select the type, enter your data, choose your dimensions, and the tool generates a high-quality PNG image that you can use immediately. It's that straightforward.
Why Use an Online Barcode Generator?
Using an online barcode generator offers several compelling advantages over desktop software or manual barcode creation methods. First, there is zero setup — the tool runs in your browser, so you can start creating barcodes instantly from any computer, tablet, or phone with an internet connection. Second, online tools are always up to date with the latest barcode standards and encoding algorithms, so you don't need to worry about compatibility. Third, they are far more convenient for one-off or small-batch barcode creation; you don't need to install, configure, and learn a complex desktop application just to generate a few barcodes. Finally, our online tool is completely free, while many desktop barcode software packages cost anywhere from $50 to $500 or require ongoing subscriptions.
