ZenQR generates and scans QR codes right in your browser. Your data is never sent to the developer or to any third-party service.

Generate

QR code for the current tab, a selected link or text, or anything you type

Templates for WiFi networks, contact cards (vCard), email, SMS, phone numbers, and calendar events

Batch-generate many QR codes at once, one per line of text

Adjustable error correction level, image size, finder/module style, and an optional embedded logo

Scan

Scan a QR code in any image from the right-click menu

Select any region of the page to scan

Paste an image from the clipboard to scan it

Scan with your camera (camera access is only requested if you use this feature)

Privacy and more

History of everything you've generated or scanned, stored only in your browser, with import/export to a JSON file

No accounts, no analytics, no tracking. Generating and scanning work offline; the only network request ZenQR may make is reloading an image you chose to scan from its original web address
