What is this Tool?
The QR Code Generator creates scannable QR codes for URLs, plain text, email addresses, and phone numbers instantly. QR codes (Quick Response codes) are 2D barcodes that smartphones can scan with their cameras to instantly open a URL, dial a phone number, send an email, or display text. They bridge the physical and digital worlds and have become ubiquitous in marketing, payments, restaurants, business cards, and public information systems.

Frequently Asked Questions
How do I generate a free QR code online?
Use this free online QR code generator — select your content type (URL, text, email or phone), enter your content and click Generate. Your QR code appears instantly and can be downloaded as a PNG image. No signup, no watermark, no cost — ever.
Can I create a QR code for a website URL?
Yes — select URL as the content type, paste your website link and click Generate. The QR code will open that URL when scanned with any smartphone camera. This is the most common use case — business cards, flyers, restaurant menus and product packaging all use URL QR codes.
Are QR codes free to use?
Yes, QR codes are completely free to create and use forever. There is no licensing fee. The QR code standard is open and can be read by any smartphone camera without any special app.
How much data can a QR code store?
The largest QR code (version 40) can hold up to 7,089 digits, 4,296 alphanumeric characters or 2,953 bytes. Longer content makes the code denser and harder to scan, so keep URLs and text short where you can.
Do QR codes expire?
Static QR codes (like the ones generated here) never expire. Dynamic QR codes — which can be edited after creation — may have expiry dates depending on the service. For a permanent, free solution, static QR codes are ideal.
What size should I print a QR code?
A common rule of thumb is at least 2 × 2 cm for close-range scanning, and larger for posters or signs read from a distance. Keep a white border around the code and always test-scan your printed copy before printing in bulk.
How do I create a WiFi QR code?
Choose WiFi, enter your network name (SSID) and password, pick the security type (usually WPA/WPA2) and click Generate. Guests can scan it with their phone camera to join without typing the password.
Is it safe to make a WiFi QR code here?
Yes. The QR code is created in your browser using the open-source QRCode.js library — your network name and password aren't sent to any server. Anyone who scans the printed code can join your network, so only display it where you'd share the password anyway.
Can I track how many people scan my QR code?
Not with a static QR code like these — they simply contain your link or text. Scan tracking needs a dynamic QR code from a paid service, or you can use a link with tracking parameters and check your website analytics.
Should I use a QR code for UPI payments?
For payments, use the official QR code from your bank or UPI app, which is linked to your verified account. Always check the name shown on screen before paying anyone by QR.
