QR Code Tool
Make QR codes that actually stay private. Your WiFi password, contact info—none of it leaves your browser.
Codes are generated locally, so the payload is not sent to a third party. A printed code is readable by anyone with a camera, so treat its contents as public and avoid embedding live credentials.

Frequently Asked Questions
Which QR code types can I generate?
Text, URLs, WiFi credentials, vCards, emails, and phone numbers.
Is the content sent anywhere?
No. QR codes are generated locally in your browser and the content never leaves your device.
Can I scan existing QR codes?
Yes — drop in a screenshot or photo of a QR code and it decodes locally. There is no camera permission prompt, so there is nothing to approve.
What does the error-correction level change?
A higher level lets the code survive more damage, but it needs more modules for the same content. The preview updates when you change the level, so you can compare density and scan reliability.
Why does a longer URL produce a denser code?
Each QR version has a fixed module grid, so more characters require a larger version or a denser arrangement. If the result becomes hard to scan, shorten the URL or render the code at a larger size.
