QR Code Generator

Create professional QR codes for a wide range of data types including URLs, plain text, Wi-Fi network credentials, email addresses, and vCard contact information — all generated entirely in your browser with no data sent to any server.

QR codes (Quick Response codes) have become an essential bridge between physical and digital experiences. From restaurant menus and event tickets to business cards and product packaging, QR codes let people access information instantly by pointing their smartphone camera at a printed code. This tool makes it easy to generate high-quality QR codes for any purpose without signing up for an account or installing any software.

The generator supports multiple data types, each optimized for its intended use case. URL mode creates a code that opens a web link when scanned — perfect for marketing materials, print ads, packaging, and business cards. Text mode encodes arbitrary text that is displayed to the scanner. Wi-Fi mode generates codes that auto-connect compatible devices to a wireless network by encoding the SSID, password, and encryption type — ideal for offices, cafes, and events where you want to share Wi-Fi access conveniently. Email mode creates a code that opens the device's email client with a pre-filled recipient address. vCard mode encodes full contact information (name, phone, email, company, address) that can be saved directly to the scanner's address book with a single tap.

Error correction is a built-in feature of the QR code standard that allows codes to remain scannable even when partially obscured, damaged, or printed at low quality. Four levels are available: Low (L) recovers 7% of data, Medium (M) recovers 15%, Quartile (Q) recovers 25%, and High (H) recovers 30%. Higher error correction levels produce denser codes with more modules, which means the QR code image itself is larger and more complex. For most use cases, Level M provides a good balance between redundancy and scannability. Choose Level H if you plan to place a logo in the center of the code or if the code will be printed on materials that may get worn or dirty.

Download options include PNG for general web and print use at the pixel dimensions you specify, and SVG for scalable vector output that remains razor-sharp at any size — from a small business card print to a large-format banner. SVG output is particularly recommended for professional printing because it eliminates any risk of pixelation or blurriness, regardless of how much the code is scaled up.

All QR code generation happens entirely in your browser using JavaScript. Your data — whether it is a URL, Wi-Fi password, email address, or contact information — is never transmitted to any server. This makes the tool safe for encoding sensitive information like internal network credentials or private contact details. No usage data is logged, no cookies are set, and no account is required.
