QR Code Generator — Free Online Tool

📱 QR Code Generator

QR codes have become a standard way to bridge print and digital — on a menu, a business card, a poster or a product label — by letting anyone with a phone camera jump straight to a link, a piece of text, or contact details without typing anything. This generator turns any text or URL you enter into a scannable QR code instantly, right in your browser.

Once generated, you can download the QR code as a PNG image ready to drop into a flyer, business card or webpage.

How a QR code encodes data

A QR (Quick Response) code stores data in a two-dimensional grid of black and white squares, using error-correction encoding so the code can still be read correctly even if part of it is damaged, dirty, or partially obscured. The pattern of squares directly encodes the bytes of your text or URL according to the QR code standard, and any standard QR scanner (including most phone cameras) can decode it back into the original text instantly.

Frequently asked questions

Do QR codes expire?

No — a standard QR code generated this way encodes your text or URL directly into the image itself, so it works forever and doesn't rely on any external service staying online. If the URL it points to changes or goes offline, though, the QR code itself won't update — you'd need to generate a new one.

What's the maximum amount of text a QR code can hold?

QR codes can hold up to a few thousand characters depending on the QR version and error-correction level used, though for reliable scanning it's best to keep the content reasonably short — a URL or short piece of text scans faster and more reliably than a very long block of text.

Can I print this QR code?

Yes — download it as a PNG and it will print cleanly at most sizes. For best scan reliability, print it at least 2–3 cm (about an inch) wide, with good contrast and no glare over the code.
