QR Code Generator Pro

Q: Which format is best for printing QR codes?

For printing, SVG is the best choice because it scales without losing sharpness. For digital use, PNG works perfectly and is widely compatible.

Q: Do these QR codes ever expire?

No. These are static QR codes — the data is encoded directly into the pattern. They will work forever as long as the linked content remains active.

Q: Is my data safe while generating a code?

Yes. Your data never leaves your browser. The QR code is generated locally on your device, ensuring complete privacy for WiFi passwords, personal links, and other sensitive information.

Q: What types of QR codes can I create?

You can encode any text or URL. Common uses include website links, WiFi credentials, vCard contact details, plain text messages, email addresses, and phone numbers.

Q: What is the ideal size for a QR code?

The rule of thumb is 1:10 — the QR code should be at least one-tenth the scanning distance. For a 1-meter scan, print at least 10 cm wide.

Q: Can I customize the colors?

Yes. Choose Standard (dark dots on light background) or Inverted (light dots on dark background). For best scanning reliability, maintain high contrast between the dot and background colors.

Q: Will the QR code work on all phones?

Yes. Modern iOS and Android cameras natively scan QR codes without an app. Older devices may need a dedicated QR scanner app.

Create high-quality QR codes for URLs, WiFi credentials, vCards, and plain text. Choose standard or inverted colors. Free, private, and instant — no signup required.

Your QR Code is Ready

All generation happens locally — your data never leaves your device.

100% Private & Secure: QR codes are generated entirely in your browser using a client-side JavaScript library. Your URLs, WiFi passwords, and vCard details are never transmitted to any server — not even ours.

What Is a QR Code?

A QR (Quick Response) code is a two-dimensional barcode that stores data in a grid of black-and-white squares. Unlike a traditional 1D barcode — which only holds a few numeric digits — a QR code can store URLs, WiFi credentials, contact cards, and up to 4,000+ characters of text. The pattern is read by almost every modern smartphone camera in under a second, which is why QR codes have become the standard bridge between the physical world and the digital world.

This tool generates static QR codes — meaning the data is encoded directly into the pattern itself. There's no redirect through our servers, no expiry date, and no dependency on our infrastructure. Once you download it, the QR code will work for as long as the linked content remains valid.

Static vs Dynamic QR Codes

Feature	Static (Our Tool)	Dynamic (Paid Services)
Where data lives	Inside the QR pattern	On a redirect server
Cost	Free forever	Monthly subscription
Expiry	Never	Expires if subscription lapses
Edit destination	No — must regenerate	Yes — change destination on the fly
Scan tracking	No tracking	Analytics dashboard
Privacy	Complete — no data leaves device	Scan data passes through provider
Best for	Permanent links, WiFi, vCards	Marketing campaigns, A/B tests

Pro Tip: For print, keep the QR code at least 2 cm × 2 cm and maintain a quiet zone (blank margin) of about 4 modules around the pattern. Always test the printed code with two different phones before final production — phone camera quality varies.

Frequently Asked Questions

Which format is best for printing QR codes?

For printing, SVG (vector) is technically best because it scales to any size without pixelation. Our tool currently exports PNG at 256×256 px, which is fine for business cards, flyers up to A5, and most digital uses. For large banners, upscale the PNG with a vector tool or generate at higher resolution.

Do these QR codes ever expire?

No. These are static QR codes — the data is encoded directly into the pattern. They will work forever as long as the linked content (like a URL or WiFi network) remains active. There is no redirect server involved, so nothing can expire.

Is my data safe while generating a code?

Yes, completely. Your data never leaves your browser. The QR code is generated locally on your device using client-side JavaScript, ensuring total privacy for sensitive information like WiFi passwords or personal contact details.

What types of QR codes can I create?

Six types: URL (website links), plain Text, WiFi credentials, Email (with subject line), Phone number, and vCard (contact card). Each encodes data in a special format that phones recognize automatically.

What is the ideal size for a QR code?

The 1:10 rule of thumb applies — the QR code should be at least one-tenth the scanning distance. For a 1-meter scan, print at least 10 cm wide. For close-up scanning (like on a business card), 2–3 cm works fine.

Can I customize the colors?

Yes. Choose Standard (dark dots on white) or Inverted (white dots on black). For maximum scanning reliability, always maintain high contrast between the dots and the background — light gray on white or dark gray on black can confuse some scanners.

Do I need to create an account?

No account, no email, no signup. Just paste your content and download the QR code immediately. There are no usage limits either.

Will the QR code work on all phones?

Yes. Every modern iOS (11+) and Android (8+) camera natively scans QR codes without an app. Older devices may need a dedicated QR scanner app from the app store.

Reviewed and maintained — The QR generation pipeline uses the QRCode.js library and has been tested with iOS Camera, Android Camera, and dedicated scanner apps. Found a code that won't scan? Send us the test case. Last reviewed: October 2026.
