How to Generate a Barcode
Choose a Barcode Format

Choose the Right Format
Use EAN-13 or UPC-A for retail products, Code 128 for general purpose, and ITF-14 for shipping cartons. Using the wrong format may prevent scanners from reading your barcode.
Maintain Quiet Zones
Always keep adequate white space (quiet zones) on both sides of the barcode. This helps scanners identify where the barcode begins and ends. Use a margin of at least 10px.
High Contrast Colors
Dark bars on a light background work best. Black on white is ideal. Avoid red bars as most laser scanners use red light and cannot read them. Blue and green bars work well.
Don't Scale Too Small
Ensure your barcode is large enough to be reliably scanned. Minimum recommended size varies by format, but generally keep the height above 15mm and maintain the original aspect ratio.
Use SVG for Print
When printing barcodes, always use SVG format. Unlike PNG, SVG barcodes can be scaled to any size without losing quality, ensuring crisp bars at any resolution.
Test Before Printing
Always test your barcode with a scanner before printing in bulk. Print a sample and verify it scans correctly with the equipment your system uses.
A Free Online Barcode Maker for Every Format
Looking for a fast, no-nonsense way to make a barcode for free? This is a complete barcode maker and barcode creator that runs entirely in your browser. Unlike many tools that hide the download behind a paywall or stamp a watermark across your image, our free barcode generator lets you create a barcode, customize it, and download a clean PNG or SVG at no cost and with no sign-up. There is no software to install and no account to register — just choose a format, type your value, and your barcode appears instantly.
Because it is a fully online barcode generator, it works on any device — Windows, Mac, Chromebook, iPhone, or Android — straight from your web browser. Everything is processed locally, so when you create a barcode here, your product codes and data never leave your computer. That combination of privacy, speed, and zero cost makes it a practical barcode generator free of the usual limitations, whether you are labeling a single item or preparing a full product catalog.
Think of it as an all-in-one barcode designer online: change the bar and background colors, set the width and height, toggle the text label, and preview the result live before you export. Because you can create a barcode online and reuse it as often as you like, it is also the simplest way to get free barcodes for testing, prototypes, price tags, and internal SKUs. Prefer a mobile workflow? The same barcode maker online loads on your phone, so you can generate and share a code on the go without any app.
UPC Code Generator: Create UPC-A Barcodes Free
Selling physical products in the United States or Canada almost always means you need a UPC barcode. Our UPC generator makes it simple to generate a UPC barcode in the UPC-A format that retailers and marketplaces like Amazon, Walmart, and Target require. As a dedicated UPC code generator, it takes your 12-digit product number and produces a scannable, standards-compliant barcode ready for your packaging or label sheet.
To use the UPC maker, select "UPC-A" as your format and enter your 11-digit product number — the tool automatically calculates the 12th check digit for you. This is the quickest way to generate a UPC label for retail, and it doubles as a UPC creator for testing point-of-sale systems, building mock product data, or printing shelf tags. If your business has been assigned a range of GS1 numbers, simply feed each UPC product code into the generator (or use bulk mode) to produce every barcode you need in one session. Note that for real retail sale, your UPC numbers should be purchased from GS1 so they are globally unique — this tool renders the barcode image from whatever valid number you provide.
Free EAN-13 Barcode Generator for Retail Products
Outside North America, the EAN-13 barcode is the global retail standard. This free barcode generator for EAN-13 encodes exactly 13 digits and, like the UPC tool, calculates the final check digit automatically — enter the first 12 digits and it completes the code. EAN-13 is a superset of UPC-A (a UPC-A code is simply an EAN-13 with a leading zero), so a single tool covers products for virtually every market worldwide. Best of all, it is a completely free EAN-13 barcode generator with no sign-up and no watermark — generate as many retail codes as you need and download each as a print-ready PNG or SVG.
For books and magazines, EAN-13 pairs with add-on symbols to encode extra information such as price or issue number. If you need to generate a barcode with a 5-digit supplement — the format commonly written as EAN-13 (5), EAN 13 5, or "EAN-13+5" — you create the main 13-digit EAN alongside a 5-digit EAN-5 add-on so the two symbols sit side by side on the printed label. This EAN-13 5 combination is exactly what appears on the back of most books (encoding the ISBN plus a suggested price) and on magazine covers (encoding the issue number).
To build one here, generate your EAN-13 for the main product code, then generate an EAN-5 for the 5-digit supplement and place it to the right of the primary barcode. Retail and publishing scanners read the pair together, so an EAN 13 5 label carries both the product identity and the extra data in a single scan — no special equipment required.
Code 128 and Code 39 Barcode Generator
When you are not selling in retail — for warehouses, asset tags, shipping, and internal tracking — Code 128 and Code 39 are the workhorses. Code 128 is the most versatile 1D symbology: it encodes all 128 ASCII characters (letters, numbers, and symbols) in a compact, high-density barcode, which is why it dominates logistics and inventory labels. Use our Code 128 barcode generator to encode order numbers, SKUs, or serial numbers of almost any length. If you just want a quick barcode 128 sample to test your scanner or label template, click the Code 128 example button and download the result in seconds.
Code 39 (also called Code 3 of 9) is the older industrial standard, encoding uppercase letters, digits, and a handful of symbols. It is bulkier than Code 128 but extremely reliable and widely supported by legacy scanners, which keeps it common in manufacturing, defense, and government. Our Code 39 barcode generator produces a clean, scannable symbol from your alphanumeric value with no configuration required.
Interleaved 2 of 5 and Other Formats
For shipping cartons and cases, Interleaved 2 of 5 (ITF, and its fixed-length cousin ITF-14) is the go-to numeric barcode. It packs pairs of digits together for a compact, high-density code that prints reliably on corrugated cardboard, which is why distribution centers depend on it. The generator also supports Codabar — sometimes spelled "codebar" — the self-checking format long used by libraries, blood banks, and FedEx airbills; simply select it and enter your value to generate a Codabar code in seconds.
Rounding out the set, the tool handles EAN-8 for small packages, MSI for inventory shelf labels, and Pharmacode for pharmaceutical packaging — giving you a single barcode generator that covers virtually every 1D symbology you are likely to encounter, from retail and publishing to logistics and healthcare.
Whichever format you need, the workflow is the same: pick the symbology, enter your value, adjust the size and colors, and download. That is what makes this both a beginner-friendly barcode creator and a serious tool for professionals who need to generate a barcode that scans the first time, every time.
