QR Code Generator: Create Custom QR Codes
📸 Live preview — Generate QR codes for any data.
Why Use QR Codes?
QR (Quick Response) codes are two‑dimensional barcodes that store information accessible by smartphone cameras. They bridge offline and online worlds: a printed QR code can lead users to a website, download an app, connect to Wi‑Fi, or share contact details. In 2026, QR codes are ubiquitous – used on business cards, restaurant menus, product packaging, posters, and even real estate signs. Our QR Code Generator creates high‑quality, scannable QR codes instantly, directly in your browser (no uploads). You can customize the size and download as PNG.
Typical use cases: share your website link on printed materials; encode vCard contact info for networking; generate Wi‑Fi QR codes for guests; create payment links; or add QR codes to email signatures. The QR code standard includes error correction, so even if the code is slightly damaged or obscured, it remains scannable.
Our tool uses the popular QRCode.js library, which runs entirely client‑side. It supports alphanumeric data, URLs, and structured data like WIFI:... and MATMSG:... for email. You can also encode plain text. All QR codes are generated in real time and can be downloaded as high‑resolution PNG images (the actual canvas, not a screenshot).
📌 How to Generate a QR Code (Step by Step)
- Enter data: Type or paste any text, URL, email, phone number, or structured data (e.g., WIFI:S:MyNetwork;T:WPA;P:password;;).
- Choose size: Select small (150px), medium (250px), or large (350px).
- Generate: Click "Generate QR". The code appears instantly.
- Download: Click "Download PNG" to save the QR code as a transparent‑background PNG.

⚙️ How QR Code Generation Works
We use the QRCode.js library, which implements the ISO/IEC 18004 standard. The library takes your input string, determines the appropriate version and error correction level (default: M), and generates a matrix of black and white modules. This matrix is then rendered as an HTML5 canvas element. The canvas size is set to the chosen dimension, ensuring crisp edges. The resulting canvas can be right‑clicked to save, or you can use the dedicated download button, which extracts the canvas data as a PNG.
Because the entire process is client‑side, your data never leaves your browser. This makes the tool safe for sensitive information (like Wi‑Fi passwords). The generated QR codes are compatible with all standard QR readers (iOS Camera, Google Lens, etc.).
