A QR (Quick Response) code is a two-dimensional barcode that can store various types of information like text, URLs, contact details, and more. It can be scanned by smartphones and QR code readers to quickly access the encoded information.

How do I scan a QR code?

Most modern smartphones have built-in QR code scanners in their camera apps. Simply open your camera app and point it at the QR code. You can also download dedicated QR code scanner apps from your app store.

What types of content can I encode?

You can encode almost any text-based content including URLs, plain text, email addresses, phone numbers, WiFi credentials, contact information (vCard), geographic coordinates, and more.

What's the difference between error correction levels?

Error correction allows QR codes to be readable even when partially damaged. Low (7%) is good for clean environments, Medium (15%) for general use, Quartile (25%) for outdoor use, and High (30%) for harsh conditions where damage is likely.

Which format should I choose - PNG or SVG?

PNG is perfect for web use, social media, and digital displays. SVG is ideal for print materials, logos, and situations where you need to scale the QR code to different sizes without quality loss.

Is my data safe when generating QR codes?

Yes, absolutely! All QR code generation happens locally in your browser. Your data is never sent to our servers or stored anywhere. You maintain complete privacy and control over your information.

Can I customize the appearance of my QR codes?

Yes! You can customize the foreground (dark) and background (light) colors, choose from different sizes, and select between PNG and SVG formats. You can also adjust the error correction level based on your needs.

How long do QR codes last?

QR codes themselves don't expire - they're just encoded data. However, if your QR code contains a URL, the lifespan depends on how long that website remains active. For static content like text or contact info, QR codes will work indefinitely.

No. Static QR codes encode the content directly and never expire — they keep working for as long as people can scan them.

Can I scan the QR code straight from the screen?

Yes. Any modern phone camera scans codes from a display — no printer needed.

How much data can one QR code hold?

Up to a few thousand characters. Shorter content produces simpler codes that scan more reliably from a distance.

Is my content stored anywhere?

No. Codes are generated locally in your browser — the content you type never reaches a server.
