Guides
Why QR & Barcode Studio
Private by design
Codes are generated and decoded on your device. Photos, contacts and Wi-Fi passwords are never uploaded.
Works offline
Install it as an app and keep creating, scanning and printing without a connection.
Fast and focused
No pop-ups, no interstitial ads and no forced sign-up between you and your code.
12 languages
Fully localized, including right-to-left Arabic. Your code's content is never auto-translated.
Print-ready
Vector SVG and PDF output, real-size print preview and common label sheets for A4 and Letter.
Safe scanning
Links are never opened automatically. We show the real domain and warn about phishing tricks first.
Frequently asked questions
Is QR & Barcode Studio really free?
Yes. Creating, scanning, history and printing are free and don't require an account. There are no ads in the core flows.
Do my QR codes expire?
No. We create static codes: the content is stored inside the code itself, so it keeps working forever and doesn't depend on our servers.
Is my data uploaded?
No. Generation and scanning run entirely in your browser or app. History is stored locally and you can delete it at any time.
Can I use the codes commercially?
Yes. Codes you create are yours to use on packaging, menus, posters and products without attribution.
