barcodegen.net is a free, browser-based barcode generation tool built for individuals and businesses who need reliable barcodes without the cost or complexity of dedicated software. It supports 20+ barcode formats — including Code 128, EAN-13, UPC-A, QR Code, Data Matrix, PDF417, and more — and requires no account, no installation, and no payment.
All barcode generation runs directly in your browser. Your data is never sent to our servers, and we never store the values you encode.
Generating a simple barcode online used to be surprisingly painful: paywalls after a few downloads, watermarks on free-tier output, confusing interfaces, or tools that only supported one or two formats. We built barcodegen.net because we wanted something that just works — fast, free, and honest about what it does.
Our goal is to keep the core tool free for everyone, forever. We sustain it through minimal, non-intrusive advertising — never paywalls, never watermarks, never generation limits.
Bulk barcode generation — Enter one value per line and generate hundreds of barcodes at once. Download all as a ZIP archive in a single click.
Multiple export formats — Download barcodes as PNG, SVG, JPG, or GIF. SVG output is vector-based and scales to any print size without pixelation.
Customizable output — Adjust bar height, module width, quiet zone margins, foreground and background colors, and whether to display human-readable text.
Barcode API & shareable links — Access barcodes via a direct image URL (e.g. /api/barcode/Code128/ABC-123) or share the full generator page with settings pre-loaded.
Barcode Scanner — Scan barcodes using your device camera, directly in the browser. No app download required.
Barcode Label Print — Design and print label sheets with custom layouts, ready for Avery-compatible label stock.
All barcode values you enter are processed client-side in your browser using JavaScript. Nothing you type is transmitted to our servers during normal usage. We do not log barcode content, store your input, or share your data with third parties for marketing purposes.
The only data we collect is standard, anonymous usage analytics — page views, format preferences, and feature usage — to help us understand what to improve. For full details, please see our Privacy Policy.
barcodegen.net is an independent project maintained by a small team. It started as a tool we built for our own work — generating barcodes for product labels, logistics documents, and internal asset tracking — and grew into something we decided to make publicly available.
We are not affiliated with GS1, Amazon, or any barcode standards body. We are a small team that cares about making useful tools and keeping them free.
Is this really free, forever? Yes. All barcode formats, bulk generation, and downloads are free with no limits. We are supported by unobtrusive display advertising, not paywalls or freemium tiers.
Can I use generated barcodes commercially? Yes. The barcodes you generate are yours to use however you need — for retail products, shipping labels, internal systems, or commercial packaging. No attribution required.
Does this tool store my barcode data? No. Barcode values are processed entirely in your browser. They are not transmitted to or stored on our servers during normal usage. The only exception is if you use the shareable link feature, which encodes your parameters into a URL.
What barcode formats are supported? We support Code 128 (A/B/C, GS1-128), EAN (EAN-13, EAN-8, EAN-5, EAN-2), UPC (UPC-A, UPC-E), Code 39, ITF-14, MSI Plessey, Pharmacode, Codabar, GS1 DataBar, ISBN, ISSN, ISMN, QR Code, Data Matrix, PDF417, and Aztec Code. New formats are added based on user requests.
