Frequently Asked Questions — QR Code Generator
- Why do these QR codes never expire?
- This generator creates 100% Static QR Codes. All data (link, Wi-Fi credentials, or contact info) is encoded directly into the pixel pattern. Unlike paid websites that redirect through their servers and break after a 7-day trial, our QR codes work permanently and never stop scanning.
- Does the vCard contact QR code work on both iPhone and Android?
- Yes! It generates standard vCard 3.0 formatting. When scanned with any native iPhone (iOS) or Android camera app (Samsung, Pixel, Xiaomi), the phone automatically prompts to save the contact directly into the address book without third-party apps.
- Is it safe to generate a QR code for my Wi-Fi network?
- Completely safe. The entire QR code is generated locally in your web browser using JavaScript. Your Wi-Fi password is never sent to our servers or saved anywhere.
- Can I print this QR code on posters, restaurant menus, or business cards?
- Yes. You can download high-resolution PNG images (up to 2048px) or vector SVG files, which scale infinitely with zero pixelation for professional printing.
- What error correction level should I choose when adding a logo?
- When adding a center icon or logo, our tool automatically selects Error Correction Level H (30%). This ensures mobile cameras can easily reconstruct any obscured parts and scan instantly.
