QR Code

Generate a QR code from any text or URL.

Free to use, no sign-up required. QR Code is one of 198 tools built into Xenition, alongside a chat that can use them for you.

Turns any text or web address into a QR code you can scan with a phone camera or save as an image. Common uses are menus, Wi-Fi notes, event links and business cards.

How to use QR Code

  1. Type or paste into the “Text or URL to encode…” box.
  2. Check the code that appears below; it redraws as you type.
  3. Press Download PNG to save it as qr.png.
  4. Scan it with your phone before printing to confirm it opens the right thing.

How it works

The image is drawn by the api.qrserver.com service at 240 × 240 pixels with an 8-pixel quiet margin, so your text is sent to that service; avoid encoding passwords or other secrets. The tool does not request an error-correction level, so the service’s default of L applies, which recovers roughly 7% of damaged modules.

Example

Entering https://example.com/menu returns a black-and-white 240 × 240 PNG square that a phone camera opens as that link. A longer text produces a denser grid of smaller squares in the same size.

Questions about QR Code

Why is my QR code hard to scan?

Long text packs more modules into the same square. Shorten the link, print it larger, and keep the white border around it.

Do QR codes expire?

A code like this is static: the text itself is stored in the pattern, so it works as long as the link it points to works.

What it takes

Use it from chat

You do not have to open QR Code to use it. Ask Xenition in plain language and it runs the right tool, then carries the answer into whatever you are working on — a document, a spreadsheet, a deck.
