About QR codes
What you can encode
A QR code can hold a website URL, plain text, a phone number, an email address, Wi-Fi credentials, or any short string. The most common use is a link — point a phone camera at the code and it opens the URL instantly.
This generator creates static QR codes, which never expire and don't track scans. What you encode is exactly what people get — there's no redirect service in the middle.
Why no watermark or sign-up?
Many QR generators add a logo, require an account, or route your link through their server so they can charge later or expire the code. This tool does none of that: the QR is computed locally in your browser, so it's free, unlimited, and yours forever.
Printing tips
For print, download the 1024px version and keep a quiet margin around the code. Don't scale it below about 2×2 cm, ensure strong contrast (dark code on a light background), and always test-scan before sending to print.
Frequently asked questions
Is this QR code free for commercial use?
Yes. The codes are static and generated locally — use them on products, posters, menus, or anywhere, with no licensing or fees.
Will the QR code expire?
No. Static QR codes encode your data directly and never expire. As long as the destination URL works, the code works.
Can it track scans?
No — and that's intentional. Static codes contain no tracking redirect. If you need analytics, use a link shortener as your URL before generating the code.
Is my data sent to a server?
No. The QR is computed in your browser, so the text or URL you enter never leaves your device.
