FAQ

Thanks for using our QR Code Generator!

Here is a list of common questions you may have...

Advanced Features

How does scannability detection work?
Our generator includes real-time scannability analysis. As you customize your QR code, we automatically scan it using the same algorithms found in smartphone cameras. If your design choices (like low contrast colors, complex patterns, or oversized logos) make the code difficult to read, you'll see a warning immediately — before you print or publish.
What color modes are available?
You can choose between three color modes for dots, corners, and background: Solid applies a single uniform color. Linear gradient creates a smooth transition between colors along a straight line — you can adjust the angle and add multiple color stops. Radial gradient creates a circular color transition from the center outward, perfect for creating depth and visual interest.
What dot shapes can I use?
We offer 10 unique dot styles to match your brand:
  • Square — Classic, sharp-edged modules for a traditional look
  • Rounded — Softened corners for a modern, friendly appearance
  • Extra Rounded — Fully circular dots for a playful, contemporary style
  • Dots — Small circular points with spacing between them
  • Classy — Elegant asymmetric shape with one rounded corner
  • Classy Rounded — Smooth organic shape for a sophisticated look
  • Bubbly Dots — Varied-size circles for a dynamic, organic feel
  • Hexagon — Six-sided geometric pattern for a tech-forward aesthetic
  • Octagon — Eight-sided modules for a unique geometric style
  • Circuit Chip — Tech-inspired pattern resembling microchip traces
What corner styles are available?
The three corner markers (finder patterns) can be customized separately from the dots. For the outer corner squares, choose from: Square, Rounded, or Extra Rounded. For the inner corner dots, select either Square or Dot. Mixing different styles creates unique visual effects while maintaining scannability.
Can I add a logo to my QR code?
Yes. Upload any image to place it in the center of your QR code. You can adjust the logo size (as a percentage of the QR code) and margin around it. The generator uses error correction to ensure the code remains scannable even with a logo overlay. For best results, keep logo size under 30% and use our scannability checker to verify.
What output formats and sizes are supported?
Export your QR code in PNG, JPEG, WebP, or SVG format. PNG and WebP support transparency. SVG provides infinite scalability for print. Choose from preset sizes (256px to 2048px) or set a custom dimension. Higher error correction levels (L, M, Q, H) add redundancy — H can recover from up to 30% damage but creates denser codes.

How do I get my Facebook QR code?

To get your Facebook QR code, follow these steps: Open the Facebook app on your mobile device. Tap the three horizontal lines, also known as the Menu, located in the top right corner of the screen. Scroll down until you see the option for "Settings & Privacy" and tap on it. Then, select "Settings" from the dropdown list. Within the Settings menu, look for "Profile Information" and tap on it.

If you are unable to find your QR code using the above steps, ensure you have the latest version of the Facebook app installed, as features and menu layouts can change with updates. Additionally, the availability of the QR code option may vary based on geographical location or device type. If you encounter any issues, consider checking Facebook's Help Center for more detailed guidance specific to your situation.

Where to find Facebook authentication QR code?

To find the Facebook authentication QR code, you need to enable two-factor authentication (2FA) on your Facebook account. Here are the steps to locate the QR code: 1. Log in to your Facebook account and go to "Settings & Privacy." 2. Navigate to "Security and Login." 3. Under "Two-Factor Authentication," click on "Edit." 4. Choose the "Authentication App" option and click "Continue." 5. Facebook will display a QR code that you can scan using an authenticator app like Google Authenticator or Authy. Scanning this QR code with your authenticator app will link your Facebook account to the app, allowing it to generate the 6-digit verification codes required for login. This QR code is specific to setting up two-factor authentication and should be scanned during the setup process. If you miss the QR code, you can revisit the steps above to generate a new one. Remember, the QR code is only visible during the initial setup of two-factor authentication and is not used for regular logins. Always ensure you have a backup method or recovery codes saved in case you lose access to your authenticator app.
