What is a QR Code?
A QR code (Quick Response code) is a two-dimensional barcode that encodes data as a matrix of black and white squares. Smartphones and dedicated scanners can read QR codes in milliseconds, making them ideal for sharing URLs, contact information, WiFi credentials, and other data without manual typing. Our qr code generator supports seven content types — URL, plain text, WiFi, vCard contact, email, phone, and SMS — each with a structured input form that builds the correct QR payload format automatically. The qr code generator uses the ISO/IEC 18004 standard, ensuring compatibility with all modern smartphone cameras and QR scanner apps.
How Our QR Code Generator Works
- Choose a Content Type and Fill the Form: Select the QR code type (URL, WiFi, vCard, etc.) from the dropdown and fill in the structured fields. The qr code generator builds the correct payload format for each type — for example, WiFi QR codes use the
WIFI:T:WPA;S:SSID;P:password;;format automatically. - Customise and Generate: Adjust the foreground and background colors, output size, quiet zone margin, and error correction level. Click Generate QR Code and the qr code generator processes your input entirely in your browser using the
qrcodelibrary. Your data never leaves your device. - Download SVG or PNG: The live preview updates instantly. Download the QR code as a vector SVG for print-quality output at any size, or as a PNG for digital use in emails, websites, and presentations.
QR Code Types Supported
- URL:Encodes any web address. Scanning opens the URL directly in the device's browser — the most common QR code type for marketing and product labels.
- WiFi: Encodes network name (SSID), password, and security type (WPA/WPA2, WEP, or open). Scanning connects the device to the network automatically on iOS 11+ and Android 10+.
- vCard Contact: Encodes name, organization, phone, email, website, and address in vCard 3.0 format. Scanning prompts the device to save the contact to the address book.
- Email, Phone, SMS: Encodes
mailto:,tel:, andsms:URIs. Scanning opens the device's email, phone, or messaging app with the details pre-filled.
Error Correction Levels Explained
QR codes include error correction data that allows them to be read even when partially damaged, dirty, or obscured. The qr code generator offers four levels: L (7%) — minimal redundancy, smallest code, best for clean digital displays; M (15%) — the default, good balance for most uses; Q (25%) — recommended for printed materials that may get worn; H (30%) — maximum resilience, ideal for industrial labels, outdoor signage, or codes with a logo overlay. Higher error correction levels produce denser QR codes with more modules, so choose the lowest level that meets your reliability requirements.

SVG (Scalable Vector Graphics) is a vector format that can be scaled to any size without losing quality — ideal for print materials, business cards, and large-format signage. PNG is a raster format at the specified pixel size — ideal for websites, emails, and digital presentations. The qr code generator provides both formats with every generated code.
Use L (7%) for clean digital displays where the code will not be damaged. Use M (15%) for most general purposes — it's the default. Use Q (25%) for printed materials that may get worn or dirty. Use H (30%) for outdoor signage, industrial labels, or QR codes with a logo overlay. Higher levels produce denser codes but are more resilient to damage.
Yes. The qr code generator lets you set any foreground (dark module) and background (light module) color using a color picker or hex code input. Ensure sufficient contrast between foreground and background — low contrast QR codes may fail to scan. Dark foreground on light background is the most reliable combination.
Select "WiFi Network" from the QR code type dropdown. Enter your network name (SSID), password, and security type (WPA/WPA2, WEP, or open). Check "Hidden network" if your SSID is not broadcast. Click Generate and download the QR code. On iOS 11+ and Android 10+, scanning the code will prompt the device to join the network automatically.
For digital use (websites, emails, presentations), 256px is sufficient. For print, use 512px or higher, or download the SVG which scales to any size without pixelation. As a general rule, the minimum print size for reliable scanning is 2cm × 2cm (about 0.8 inches square). Larger codes with higher error correction scan more reliably at distance.
