📖 How to Use

  1. Enter a URL or text in the box — paste a link (e.g. https://example.com) or type anything you want to encode: Wi-Fi details, contact info, event links, and so on.
  2. The QR code image updates automatically as you type — no button required.
  3. Pick an image size from the dropdown: 200×200, 300×300, or 500×500 pixels. Larger sizes scan more reliably from a distance or when printed.
  4. Download the image by clicking "Download QR Code" to save it as a PNG. If the download button doesn't work, right-click the QR code image and choose "Save image as" instead.
Note: This tool works with any text content (URLs, plain text, contact details, etc.), and the QR code image is generated on the fly by a third-party QR code service — so whatever you enter is sent over the network to that service. Avoid encoding sensitive information like passwords. QR codes also have a data capacity limit: longer content produces a denser pattern that can be harder to scan or may fail to generate, so consider using a short link for long URLs.
