How QR Code Generator works

QR codes encode data into a two-dimensional matrix of black and white squares. This tool uses the open-source qrcode.js library to generate QR codes entirely in your browser. When you enter data, the library converts it into a binary format, applies Reed-Solomon error correction (which lets the code remain scannable even when partially damaged), and renders it as a PNG image on a canvas element. The error correction level determines how much of the code can be damaged — ranging from 7% (Low) to 30% (High). Everything runs client-side; your data never leaves your device.

Frequently asked questions

Is this QR code generator free?

Yes. It is 100% free with no signup, no watermarks, and no limits.

Can I customize the QR code colors?

Yes. You can change both the foreground (dot) and background colors using the color pickers.

What dot styles are available?

Three styles: Square (classic), Rounded (softer look), and Dots (circular modules). Each changes how individual data modules are drawn.

Can I add a logo to the QR code?

Yes. Upload any PNG or SVG image and it will be embedded in the center. Use H (High) error correction so the code remains scannable despite the logo covering ~22% of the area.

What are corner frame and corner eye options?

The three finder pattern squares in the corners can be styled separately — Square, Rounded, or Extra-Rounded frames, and Square or Dot center eyes.

What formats can I generate QR codes for?

URLs, plain text, WiFi credentials, email addresses, phone numbers, and SMS messages.

Can I download the QR code?

Yes. Download your QR code as a high-resolution PNG image with one click.

Do the QR codes expire?

No. QR codes generated here are static and never expire. They contain the data directly with no redirect server involved.

Is my data stored or tracked?

No. The QR code is generated in your browser. Your content is not sent to a server.

Is there a size or content limit?

Very long text creates dense codes that can be harder to scan. Keep content concise for best results.
