CREATION FEATURES

Text QR Codes

Generate QR codes containing any text content. Useful for notes, messages, or any information you want to encode.

URL QR Codes

Create QR codes for website addresses. The app automatically validates the URL format and adds https:// if needed. When scanned, these codes can open directly in a web browser.

Email QR Codes

Generate QR codes that contain email addresses in mailto format. When scanned, these can open the default email app with the address pre-filled.
