About this tool
QR Code Generator creates QR codes entirely in your browser using the local QR encoder. No data is uploaded. For best scan reliability, use high contrast colors.
- Create QR codes from plain text or URLs (URLs are normalized automatically).
- Choose an error-correction level (L, M, Q, H) and an output size from 128 to 1024 px.
- Customize foreground and background colors, with a low-contrast warning for scan reliability.
- Download the result as PNG on your device — text never leaves the browser.
FAQ
Is the QR Code Generator free?
Yes completely free, no account, no watermark, no daily limit. It runs entirely inside your web browser.
Is my data uploaded to a server?
No. The QR code is generated entirely in your browser using local cryptographic encoding. No text or URL you enter is transmitted or stored.
What can I use the QR code for?
You can use the generated QR code to connect to WiFi networks, share links, store contact information (vCard), or any other purpose a QR code supports. High contrast colors are recommended for best scan reliability.
Which error correction level should I choose?
Level M (Medium) is recommended for general use. Level H (High) restores up to 30% of codewords if damaged, while L (Low) and Q (Quartile) use less data and produce smaller codes. Choose H if the QR code will be exposed to wear or dirt.
