What is QR Code Generator?
A QR code is a square, scannable barcode that stores information such as a website link, plain text, contact details or Wi-Fi credentials. A QR code generator turns whatever you type into a scannable image that any smartphone camera can read instantly. This tool creates the code entirely in your browser and lets you download it as a PNG.
You can adjust the size, colours and error-correction level, then use the finished code on posters, business cards, packaging or websites.

Benefits & Use Cases
Businesses link customers to menus, websites and payment pages, while individuals share contact details and Wi-Fi access without typing. Higher error correction lets a code still scan even if part of it is damaged or covered by a logo.
Because the QR code is created locally, sensitive links and data are never uploaded, making this a private, reliable alternative to online generators that track your input.
The QR Code Generator is completely free, needs no sign-up or installation, and runs entirely in your browser — nothing you enter is uploaded to a server, so your data stays private. It works on desktop, tablet and mobile, in light or dark mode.
Tips & Best Practices
Raise the error-correction level when the code will be printed small, placed on a curved surface or overlaid with a logo — the extra redundancy lets it still scan if part is damaged. Keep strong contrast (dark on light works best) and leave the quiet border intact so cameras lock on quickly.
Encoding a link? Tidy it first with the URL Encoder / Decoder. After downloading, resize or convert the PNG for print or web with the Image Format Converter.
FAQ about QR Code Generator
What can I put in a QR code?
Any text works — website links, plain messages, phone numbers, email addresses or Wi-Fi details formatted as text. Most people encode URLs.
What does error correction do?
Higher error correction adds redundancy so the code still scans even if it is partly damaged or obscured, at the cost of a slightly denser pattern.
Can I change the colours?
Yes. You can set custom foreground and background colours, though keeping strong contrast ensures the code scans reliably.
Is my data sent to a server?
No. The QR code is generated entirely in your browser, so whatever you encode stays completely private.
