QR Code Generator

QR codes use Reed-Solomon error correction, which means part of the code can be damaged, smudged, or partially obscured by a logo and still scan correctly, up to a configurable percentage depending on the error correction level chosen. Higher error correction makes the code denser and more visually complex, but more resilient, which is the tradeoff designers are making whenever they print a logo in the center of a code.

A long website URL printed on a flyer rarely gets typed out by a potential customer standing in front of it, that friction kills the conversion. A QR code removes the typing step entirely. The same logic applies at a networking event, handing someone a scannable vCard code gets your contact details into their phone before the conversation ends, instead of relying on them manually saving a photo of your business card later.

Choose what you're encoding, a plain URL, text, or a full vCard with name, phone, and email, and the preview updates as you type. Once it's complete, download a high-resolution PNG that holds up cleanly even at a larger print size.

Contrast matters more than most people expect: a scanner needs clearly distinguishable dark modules against a light background, so while recoloring a code is fine, keep enough contrast between the foreground and background or scanners will struggle. All of the encoding happens locally in your browser, so the phone number or email you're putting into a vCard never gets uploaded anywhere first.
