QR code generator

Your QR content stays on your device

Options and help

Higher error correction makes a denser QR code. Shorter content and larger images are easier to scan. The white border is kept for scanning.

These are static QR codes: their encoded content cannot be changed after sharing. Scanning behavior depends on the camera or app. Test before printing or sharing.

A Wi-Fi QR code contains the network password. Anyone who scans it can read that information. QR content is not uploaded; only anonymous run IDs, durations and error codes are recorded.

What to know

These static QR codes encode data directly and cannot be edited after sharing. Scanner support varies. Wi-Fi passwords are readable from the QR code. Limit: 1,200 UTF-8 bytes per code and 100 codes per batch.
