QR Code Generator

Enter any text, URL, or message to instantly generate a scannable QR code you can download and use.

QR Code Generator

Live
Generated via a public QR image service based on the text you enter - your text isn't stored by this page, but is sent to that service to render the image.

How it works

Your text is URL-encoded and sent to a QR image rendering service, which returns a QR code image encoding that exact text
Note

Any text works - a URL, plain message, phone number, or Wi-Fi network details in the correct format will all generate a valid, scannable code.

Step-by-step guide

  1. Enter the text or URL you want the QR code to contain.
  2. Choose a size - larger sizes print more clearly at bigger physical dimensions.
  3. Download the image once it looks right, and test-scan it with your phone before using it anywhere important.

Why the text field affects reliability, not just content

Longer text requires a denser QR code pattern to encode, which can make the code harder to scan reliably at small print sizes - a QR code containing a short URL scans more easily and from farther away than one containing a long paragraph of text. If you're printing a QR code for physical use (a flyer, product packaging, a sign), consider using a URL shortener for long links, and always test-scan the final printed result before distributing it widely.

Common mistakes

Not testing the QR code before printing or publishing it widely - always scan it yourself first to confirm it opens the right link or shows the right text.
Printing a QR code too small, or with low contrast between the code and background - both make scanning unreliable, especially from a distance or in poor lighting.

Frequently asked questions

Do QR codes expire?

No - a QR code generated this way encodes your exact text permanently and will keep working as long as the image exists. If it links to a URL, though, the code keeps working only as long as that destination URL itself stays valid.

Can I put Wi-Fi network details in a QR code?

Yes - many phones recognize a specific format (WIFI:T:WPA;S:NetworkName;P:Password;;) and will offer to join the network directly when scanned, though exact support varies by phone and QR scanner app.

Is there a limit to how much text a QR code can hold?

QR codes can technically hold a few thousand characters, but practically, shorter content (especially a short URL) scans faster and more reliably, particularly at smaller print sizes.
