Free QR Code Generator for Text, Wi-Fi, vCard, Email, and SMS

This CoinStori Toolkit helps you create professional QR codes directly in your browser. You can generate QR codes for websites, plain text, Wi-Fi credentials, digital business cards (vCard), email links, and SMS messages. The tool also supports design customization (dots, corners, colors), optional logo overlays, and high-quality exports for web and print.

What you can create with this QR code generator

  • Text / URL: Share links, landing pages, documents, or any custom message.
  • Wi-Fi QR: Let guests connect instantly without typing SSID/password.
  • vCard (Business Card): Share name, phone, email, company, and job title.
  • Email: Open a pre-filled email draft with subject and body.
  • SMS: Start a text message with an optional pre-filled message.

How to generate a QR code (best-practice workflow)

  1. Select a QR type (Text/URL, Wi-Fi, Business Card, Email, or SMS).
  2. Enter your details and confirm everything is correct (especially phone numbers and Wi-Fi SSID).
  3. Choose a style preset or customize dot/corner shapes and colors.
  4. (Optional) Upload a small, high-contrast logo for the center area.
  5. Export in the right format for your use case (SVG for design, PNG for web, PDF for print).

Design and scanning reliability (important)

For maximum scan performance, keep strong contrast between the QR code and its background, and avoid overly complex styles. If you add a logo, use a smaller logo and prefer higher error correction. Always test your final QR on multiple devices (iOS/Android) and in different lighting conditions.

Export format guide

SVG

Best for designers and scalable assets. Stays sharp at any size.

PNG

Great for websites, social posts, and presentations. Use for most online use cases.

JPEG

Useful when you need smaller file sizes, but may blur at high compression.

PDF

Best for printing flyers, packaging, posters, and labels.

Privacy and security notes

This tool is designed to be privacy-friendly: your input is used to generate the QR code in your browser. If you encode sensitive information (for example, Wi-Fi passwords or personal contact details), only share your QR code where appropriate, and consider using a dedicated guest network for public access.

FAQ

Will my QR code expire?

No. A QR code is static unless it points to a URL that changes or becomes unavailable.

Which format should I choose for printing?

Use PDF for print workflows, or SVG if your designer wants fully scalable vector output.

Why is my QR code hard to scan?

Common causes: low contrast, too small size, busy background, excessive styling, or an oversized logo.

Does Wi-Fi QR work on all phones?

Most modern phones support it. Always test on both iOS and Android devices before publishing.

Built for practical use: marketing assets, event check-ins, product packaging, business networking, and Web3 community campaigns.
