QR codes turn any link or text into a scannable square that phone cameras read in a fraction of a second — no app needed on modern phones. Restaurants use them for menus, businesses for WiFi passwords and payment links, creators for channel URLs. This free generator creates crisp, high-error-tolerance QR codes entirely on your device: your text is never uploaded, logged, or tracked.
Every code includes a quiet-zone border and is rendered at print-friendly resolutions up to 800px, so it scans reliably from screens, paper flyers, and product packaging alike. Because the encoding happens locally with JavaScript, the tool also works fully offline — handy at events with spotty WiFi.
For best scan rates, keep URLs short (use a link shortener for very long addresses), ensure good contrast when printing, and test the code with your own phone before publishing it.
How to use the QR Code Generator
- Type or paste your text or URL into the input box (up to 230 characters).
- Choose an image size — medium for screens, large for print.
- Click Generate QR code to render it instantly.
- Test it by pointing your phone camera at the code.
- Download the PNG and use it anywhere: flyers, packaging, business cards, slides.
Tips for accurate results
- Short URLs scan faster and produce cleaner, less dense codes.
- Always test-scan before printing hundreds of copies.
- Keep a quiet margin (white space) around the code — don't crop it edge-to-edge.
- For WiFi sharing, format as WIFI:T:WPA;S:NetworkName;P:password;;
What can you put in a QR code?
Almost any short text: website URLs, plain messages, email addresses (mailto:), phone numbers (tel:), SMS, geographic coordinates, and WiFi credentials in the special WIFI:T:...; format. Phone cameras recognize these schemes automatically and offer the right action.
Frequently asked questions
Are QR codes free to use commercially?
Yes. The QR code standard itself is open and royalty-free; codes you generate here are yours to use anywhere, including commercial print.
Do QR codes expire?
No — a static QR code like the ones made here encodes the text directly and works forever. (Dynamic QR services with tracking can expire, but this tool makes static codes.)
Is my data uploaded when I generate a code?
No. Generation happens 100% in your browser with JavaScript. Nothing leaves your device.
Why won't my QR code scan?
Usual causes: too-small print size, low contrast, a damaged/curved surface, or an over-long URL making the code too dense. Regenerate larger and test again.
