Preguntas frecuentes

Is my data safe?
Yes. All processing happens entirely in your browser. Your data never leaves your device and is never uploaded to any server.
What can I encode in a QR code?
Any text, URL, email address, phone number, or Wi-Fi credentials. The QR code can store up to about 4,000 characters of text or roughly 7,000 numeric digits.
Can I use the QR code commercially?
Yes. Generated QR codes are free to use for any purpose, including commercial use. There are no licensing restrictions.
Do QR codes expire?
No. The QR code itself is just an encoded image — it never expires. However, if it encodes a URL, the QR code only works as long as that URL is live.
What size should I print the QR code?
For reliable scanning, print QR codes at least 2cm x 2cm (about 0.8 inches). For scanning from a distance (posters, banners), make them larger — roughly 1/10th the expected scanning distance.

Consejos y buenas prácticas

  • 💡Keep URLs short — shorter content produces simpler QR codes that are easier to scan from a distance or at small sizes.
  • 💡Test your QR code by scanning it with at least two different phone cameras before printing. Not all cameras handle complex QR codes equally.
  • 💡For print materials, generate the QR code at the largest reasonable size. QR codes smaller than 2cm x 2cm can be difficult to scan.
  • 💡Use URL shorteners for long links to create cleaner, more scannable QR codes. But make sure the shortener is reliable long-term.

Cómo se compara

Many free QR code generators like QR Code Monkey or QRCode Generator require creating an account for advanced features and may track your generated codes. Some add their branding to the QR image. TinyTool generates QR codes entirely client-side with no tracking, no account requirement, and no watermarks. For advanced customization like colored QR codes or logo embedding, dedicated QR tools offer more options, but for fast, private, no-fuss QR generation, client-side is the way to go.
