I built a free barcode & QR code generator — no backend, no signup, runs 100% in the browser
I wanted a clean, fast tool that works entirely in the browser. No backend, no tracking, just pure client-side code.
What it supports:
- Barcodes: EAN-13, CODE128, UPC-A, CODE39, ITF-14, EAN-8
- QR Codes: URL, WiFi, vCard, Email, Phone, Location & Events
- Bulk generation via CSV / Excel import
- Camera barcode scanner
- PNG & SVG download
- Custom colors + logo on QR codes
- PWA — works offline
- 6 languages (TR, EN, DE, FR, ES, AR)
Built with vanilla JS — no framework, no dependencies except JsBarcode and QRCode.js.
Would love your feedback!

Nice work — especially the fully client-side approach, that’s super clean 👍
I’ve been exploring a somewhat related space (labels / barcodes), and one interesting thing I’ve noticed is how different the use cases actually are.
Tools like yours are perfect for quick generation — like creating a barcode or QR once and downloading it as PNG/SVG.
But when it comes to real workflows (inventory, shipping, product labeling), the problem shifts quite a bit:
people already have structured data (often in spreadsheets), and the challenge becomes generating hundreds of labels consistently and printing them with the correct physical dimensions.
Surprisingly, even something as simple as printing a correctly sized label from a PDF to a thermal printer isn’t obvious to many users.
So it feels like there’s a big gap between:
“generate a code” → and → “operate a labeling workflow at scale”
Curious if you’ve thought about that side of the problem, or if you’re intentionally focusing on quick generation only?
