About QR Code Generator
This tool can generate QR codes for links, plain text, WiFi credentials, email addresses, phone numbers, and UPI payment links directly in the browser.
The QR code image can then be downloaded as PNG after generation, and the library itself supports in-browser rendering without needing a backend request for the code image.
Tips for a reliable QR code
- Keep strong contrast between QR color and background — dark on light works best for scanning reliability.
- Avoid making the code too small when printing; test-scan it from the intended distance before mass printing.
- For WiFi and UPI codes, double-check the details before downloading, since errors will be encoded directly into the image.
- Higher size settings produce a sharper code, which helps scanners read it correctly even in low light.
Frequently Asked Questions
Yes, it's completely free with no sign-up required. You can create and download unlimited QR codes for URLs, text, WiFi, email, phone, and UPI.
No, these are static QR codes that encode your data directly into the image, so they don't expire as long as the underlying information (like a URL) stays valid.
PNG is ideal for most uses including sharing, printing, and documents, since it stays sharp at any size without compression artifacts.
Select the WiFi tab, enter your network name, password, and security type, then generate. Guests can scan it to join automatically without typing the password.
Yes, set a custom QR color and background color before generating. Keep enough contrast between them so scanners can still read the code reliably.
Usually caused by low contrast between colors, too small a print size, or distorted proportions after resizing. Use high-contrast colors and a reasonably large size.
It encodes your UPI ID, payee name, and optionally a fixed amount into a payment link. Any UPI app can scan it to pre-fill payment details for the user to confirm.
