About BarcodeGenerate
A free, browser-based barcode and QR code generator. No account required, no data uploaded — everything runs in your browser.
Our Mission
Barcode generation shouldn't require expensive software, subscriptions, or technical expertise. Our goal is to provide a fast, accurate, and completely free tool for anyone who needs to create barcodes — from small business owners labeling products to developers testing barcode systems.
We built BarcodeGenerate because existing tools were either too expensive, too complicated, or cluttered with dark patterns that obscured simple functionality. We wanted something straightforward: enter your data, get your barcode.

Privacy First
Your barcode data never leaves your browser. All barcode generation happens client-side using JavaScript — nothing is sent to our servers. This means:
- No account or sign-up required
- No data collection beyond standard analytics
- Generated barcodes are not stored or logged
- Works offline once the page has loaded
Built With
BarcodeGenerate is built with modern web technologies that prioritize performance and simplicity:
The site is deployed on Cloudflare Pages for fast global delivery and 100% uptime.
How BarcodeGenerate Works
When you enter data into the generator, our JavaScript library renders the barcode directly in your browser as an SVG element. There is no round-trip to a server — the barcode appears instantaneously because the computation happens on your device. This architecture has two major benefits: speed (no network latency) and privacy (your data never leaves your browser).
For barcode scanning, we use the Web BarcodeDetector API (in supported browsers) with ZXing-WASM as a fallback, enabling accurate decoding of both 1D and 2D barcodes entirely client-side. Scanned data is displayed in your browser and never transmitted anywhere.

Frequently Asked Questions
Is BarcodeGenerate really free?
Yes. All core tools — barcode generator, QR code generator, and barcode scanner — are completely free with no registration required. A Bulk Generator feature for CSV batch generation is available as a one-time $4.99 purchase.
Is my data secure when I generate barcodes?
All barcode generation and scanning happens entirely in your browser. Nothing you type or scan is ever uploaded to our servers. The site operates fully offline once loaded, and we do not log the barcodes you create.
Can I use the generated barcodes commercially?
You own the barcode images you generate. For retail products (EAN-13, UPC-A), the barcode number must be a registered GS1 number. For internal or non-retail use (inventory, shipping, QR codes), there are no restrictions.
