QR Code Anatomy
▶Finder Patterns — the three large squares in the corners. They let the scanner detect the code's orientation and size instantly.
▶Alignment Patterns — smaller squares that keep the code readable even on curved or distorted surfaces.
▶Timing Patterns — dotted lines between finder patterns that help identify individual data cells.
▶Data Modules — the black and white squares that actually encode your content.

Frequently Asked Questions
Are QR codes free to create and use?
Yes. QR codes are an open standard (ISO/IEC 18004). You can generate them free on ThinkForU and they never expire as long as the destination URL is active.
Do QR codes expire?
Static QR codes (like the ones generated here) do not expire. The data is hard-coded into the pattern. Dynamic QR codes may expire if the provider's subscription ends.
Can I change the link after printing?
No — for static QR codes the link is baked into the image. To update the destination after printing, you need a Dynamic QR Code service.
How much data can a QR code hold?
Up to 7,089 numeric characters or 4,296 alphanumeric characters — enough for a full vCard, a long URL, or a Wi-Fi configuration.
Do I need a special app to scan QR codes?
No. Most modern Android and iOS phones have built-in QR scanners in the default camera app. Just open your camera and point it at the code.
Is my data safe?
Yes — 100% safe. All processing runs locally in your browser. Your URL, text, or contact details never leave your device or touch any server.
Can I add a logo to my QR code?
Yes. Use the logo upload option and set Error Correction to High (30%) to keep the QR code scannable even with a logo overlaid in the center.
Can I generate a QR code for a PDF?
Yes. Upload your PDF to Google Drive or Dropbox, copy the public share link, and paste it into the URL input of this generator.
