How to use
- 1
Pick a content type
Use the tabs to switch between Text, URL, Email, Phone, SMS and Wi-Fi. Each tab shows the fields relevant to that type.
- 2
Fill in the fields
Type your content. The preview updates automatically. For Wi-Fi, choose the encryption type and tick “Hidden network” if needed.
- 3
Adjust appearance
Use the size, quiet-zone, error-correction and colour controls. Higher error correction lets the code keep scanning even if partially obscured.
- 4
Download the PNG
Click Download PNG to save the QR code image to your device. The downloaded image is at the full resolution you selected.
Common use cases
- Print a Wi-Fi QR code for guests to scan instead of typing the password.
- Encode a vCard-style contact or business URL on a flyer.
- Generate a phone-call QR for a customer-support hotline.
- Pre-fill an SMS draft so attendees can quickly text a keyword to a number.
Limitations
- Output is PNG only. For SVG, use the underlying
qrcodelibrary directly. - Very long inputs may exceed QR capacity at low error-correction levels — switch to a higher level or shorten the content.
- Light-on-dark QR codes scan less reliably on some phones; keep the foreground darker than the background when possible.
