QR Code Generator — Fully Private

What is a QR Code Generator?

A QR code generator is a tool that converts text, URLs, email addresses, or other structured information into a 2D barcode format called a Quick Response (QR) code. These codes can be scanned by smartphone cameras or dedicated barcode scanners to quickly access the encoded information without manual typing.

Why use a private QR code tool?

Many free QR code generators actively track scans or require you to upload your sensitive information to their servers. For encoding confidential internal links, private Wi-Fi passwords, or personal vCard details, you need a tool that operates entirely on your device. This generator runs offline in your browser.

How to create a QR code

1. Select the type of QR code you want (URL, Text, Email, Wi-Fi, etc.)
2. Enter your information into the fields
3. Customize the code by adjusting size and error correction
4. Click Download (PNG or SVG) to save the code locally

Error correction levels explained

QR codes use Reed-Solomon error correction, allowing them to remain scannable even if partially damaged or obscured. Higher levels improve scannability but make the QR code denser:

• L (Low): Approx 7% restoration — best for simple URLs.
• M (Medium): Approx 15% restoration — standard for most uses.
• Q (Quartile): Approx 25% restoration.
• H (High): Approx 30% restoration — best for codes with logos or those exposed to wear and tear.
