QR codes are generated entirely in your browser using QRCode.js — no data is sent to any server.
Type a URL or any short text, pick 200/300/500 px and colours, then render a PNG with QRCode.js in the tab. Download only after you scan the preview with your own phone—contrast and size matter more than fancy colours.
Capacity and mistakes
- Very long strings need a denser QR matrix; extremely long payloads may fail to encode.
- Low contrast (light-on-light) or tiny print breaks phone cameras.
- The QR stores exactly what you typed—no shortening service. Changing the destination later means generating a new code.
Processing
Rendering is client-side. The payload is not posted to Nexora.
QR generation questions
What is a QR code?
A QR code is a two-dimensional barcode that stores text data and can be scanned by phones, cameras, and QR reader apps.
How do I create a QR code?
Enter a URL or text, choose size and colors if needed, generate the QR code, then download the PNG after checking that it scans.
Do QR codes expire?
Static QR codes do not expire by themselves, but a linked URL can stop working or change later.
Can I download the QR code?
Yes. After generation, use the download button to save the QR code as a PNG image.
What information can a QR code contain?
This tool accepts text or URLs. QR codes can technically store many text-based formats, but you should test the generated code in your target scanner.
