How to generate a QR code in your browser

Aiviko's QR Code Generator creates scannable URL, plain-text, and Wi-Fi QR codes directly in your browser without sending the payload to an Aiviko server. Customize foreground and background colors, quiet-zone margins, and error correction levels (L, M, Q, H), then export crisp PNG or scalable SVG files immediately.

  1. 1. Select URL, Text, or Wi-Fi mode

    Choose the payload format and enter your link, multilingual text, or Wi-Fi network SSID, security type (WPA/WPA2, WEP, or open), and password.

  2. 2. Tune colors, margin, and error correction

    Adjust foreground and background hex colors, quiet-zone padding, and error recovery while checking the live contrast warning.

  3. 3. Test and export PNG or SVG

    Scan the live preview with a phone camera to verify the payload, then download a high-resolution PNG or vector SVG.

Supported QR formats and workflows

  • Wi-Fi QR Code generation for WPA/WPA2, WEP, open networks, and hidden SSIDs so guests can join without typing passwords
  • Website URL and plain-text encoding with full Unicode, emoji, and multilingual character support
  • Instant raster PNG and vector SVG downloads with customizable quiet-zone margins and L/M/Q/H error correction
  • Live foreground/background contrast checking to prevent unreadable print or screen codes

Practical limits and scanning considerations

  • Wi-Fi QR codes store network credentials in scannable plain text; treat printed or shared images like the password itself.
  • Very long text strings increase module density, which can make small printouts harder for older phone cameras to focus on.
  • Inverted color schemes (light foreground on a dark background) or low contrast can fail on some built-in camera scanners.

Frequently asked questions about QR Code Generator

Are my Wi-Fi password or URL sent to an Aiviko server?

No. The QR payload and image pixels are generated locally in your browser memory. Standard page assets, analytics, and ads follow our published privacy policy.

Should I download PNG or SVG for printing?

Use PNG for quick sharing in documents, slides, and chat apps. Choose SVG when placing the QR code into print layouts, signage, or vector design tools so it scales without blurring.

Do generated QR codes expire or use redirect tracking links?

No. Aiviko encodes your exact URL, text, or Wi-Fi configuration directly into a static QR code without intermediary redirect links or expiration dates.
