What Is QR Generator?

A QR (Quick Response) code generator converts information into a scannable two-dimensional barcode that smartphones and other devices can read instantly. This tool supports multiple payload types including plain text, web URLs, email addresses, phone numbers, SMS messages, and WiFi network credentials. Each QR code is generated directly in your browser using client-side rendering, meaning your data stays private and never touches a server. The resulting codes follow standard QR specifications, ensuring broad compatibility with all major QR scanning apps and built-in camera readers.

How It Works

Select the type of content you want to encode from the Type dropdown — Text, URL, Email, Phone, SMS, or WiFi. Enter the primary value such as a URL, phone number, or WiFi SSID in the Primary Value field. For types that require additional information like a WiFi password or SMS body, fill in the Secondary Value field. Click "Generate QR" to create the code instantly. The QR image appears on screen, and you can click "Download PNG" to save it as an image file for printing, sharing, or embedding in documents and presentations.

Best Use Cases

• Business Cards: Add a QR code linking to your website, portfolio, or contact details for easy scanning.
• Event Marketing: Generate QR codes for registration links, venue maps, or promotional URLs on flyers and posters.
• WiFi Sharing: Create a QR code with your network name and password so guests can connect without typing credentials.
• Product Packaging: Embed QR codes on labels linking to manuals, warranty registration, or support pages.

Fields and Input Explanations

• Type: Select the QR code payload type — URL, plain text, email address, phone number, SMS, or WiFi credentials.
• Primary Value: The main content encoded in the QR code (e.g., the URL, phone number, email address, or WiFi SSID).
• Secondary Value: An additional value required for certain types (e.g., WiFi password, SMS message body, or email subject line).

Frequently Asked Questions

Is the QR Generator completely free and do I need an account?

Yes, the QR Generator is completely free to use and requires no account, login, or subscription of any kind. Open the page in any browser and generate as many QR codes as you need. There are no daily limits, no watermarks on downloaded images, and no premium tier required for any of the supported payload types including URL, text, email, phone, SMS, and WiFi credentials.

Can the QR codes I generate be scanned by any smartphone?

Yes. The codes generated by this tool follow the standard QR code specification (ISO/IEC 18004), ensuring compatibility with virtually all QR scanning apps and the built-in camera readers on Android and iOS devices. Standard camera apps on modern smartphones can scan most QR types without installing a separate app. WiFi QR codes may require a dedicated scanner on older Android versions, but iOS 11 and later handles them natively through the Camera app.

Is my data sent to any server when I generate a QR code?

No. All QR code generation happens entirely within your browser using a client-side JavaScript library. The URL, text, WiFi credentials, or other data you enter never leaves your device and is not transmitted to any external server, stored in a database, or logged for analytics. This makes the tool particularly suitable for encoding sensitive information such as WiFi passwords or internal URLs that you would not want exposed to third-party services.

Tips for Best Results

• Use high contrast when printing: Black on white gives the highest scan reliability. Avoid placing QR codes on dark backgrounds or using low-contrast color combinations, as this can cause scan failures on cameras with less sensitive optics.
• Leave a quiet zone margin: When embedding a downloaded QR code in a flyer or document, leave at least 4 modules of white space around all four sides. Without this quiet zone, scanners may miss the boundary markers and fail to decode the code correctly.
• Test before printing at scale: Always scan the generated code with multiple devices before printing hundreds of copies. Verify the destination URL loads correctly and that WiFi credentials connect successfully.
• Prefer URL type for website links: For website links, always use the URL type rather than plain Text. URL-encoded QR codes are recognized as clickable links by camera apps, while plain text codes are displayed as text strings the user must manually copy and paste.
