Free Advanced QR Code Generator

Quick Response (QR) codes have revolutionized how we share information. However, building specific types of QR codes—like ones that automatically connect your guests to your Wi-Fi, or automatically draft an email on a user's phone—requires specific string formatting. Our free, lightweight QR Code Generator automatically calculates the exact structural syntax required by smartphone cameras to trigger these actions seamlessly.

How to Use the Generator

1. Select Your Type: Use the dropdown menu to choose whether you want to generate a standard Website URL, a Wi-Fi auto-connect code, an Email, a Phone Call, or an SMS text message.
2. Enter Your Data: Fill in the newly generated input fields. Our system handles all the complex data compilation behind the scenes.
3. Customize the Design: You don't have to stick with boring black and white! Use the color pickers to match the QR code to your brand or company logo colors. You can also adjust the final download resolution from 100px up to 500px using the slider.
4. Download or Share: Once you are happy with the live preview, click Download PNG to save the high-quality image directly to your computer. Alternatively, click "Copy Link" to get a direct hosted URL to the generated image.

The Calculated Data Structures

If you look at the dark code box in the tool above, you can see the exact syntax string we compile before generating your image. Here are the universal formulas used by Apple iOS and Android OS to recognize QR commands:

• Wi-Fi Auto-Connect String: WIFI:S:[Network Name];T:[Encryption Type];P:[Password];;
• Email Drafting String: mailto:[Email Address]?subject=[Subject Line]
• SMS Drafting String: SMSTO:[Phone Number]:[Pre-filled Message]
