QR Code Generator

Generate QR codes as you type. Works for URLs, plain text, Wi‑Fi strings (WIFI:T:...), vCards, and other common QR payloads.

How to Use

  1. Enter content in the text area (URL, text, or structured payload).
  2. Adjust size and error correction if needed.
  3. Download PNG to save the image, or scan the code directly from the screen.

Features

  • Live preview while you type (short debounce for smooth typing).
  • Configurable size (128–1024 px) and error correction (L / M / Q / H).
  • Quiet zone (margin) control for scanners that need more border.
  • Download PNG with one click.

Privacy & Security

Client-side only: Content is encoded in your browser by the qrcode library (MIT), loaded once from jsDelivr. Your text is not sent to NetDevOps.it servers for QR generation.

Technical Notes

  • Capacity: Very long payloads can exceed QR limits; the tool shows an error if so.
  • Offline: After the first visit, the library may be cached by your browser; a network is still required on first load unless you self-host the script.
