QR Code Generator

The QR code — Quick Response code — was invented in 1994 by Denso Wave for automotive manufacturing logistics. Three decades later, it has become one of the most scanned symbols on earth, embedded in restaurant menus, business cards, product packaging, payment systems, event tickets and museum exhibits. A QR code can encode a URL, plain text, email addresses, phone numbers, Wi-Fi credentials, geographic coordinates or any alphanumeric string up to approximately 4,296 characters — all instantly readable by any modern smartphone camera. Our generator creates high-resolution QR codes entirely in your browser, with no data ever sent to a server, in any colour scheme you choose, downloadable as a crisp PNG image.

QR codes are most often used to encode URLs, and the quality of that URL matters enormously for both usability and search engine performance. If you are creating a QR code for a blog post, product page or any web resource, your URL should be clean, descriptive and contain relevant keywords. Our URL Slug Generator converts any title or text into a perfectly formatted, SEO-friendly slug — so the URL encoded in your QR code looks professional and supports your organic search rankings simultaneously.

For developers embedding QR codes in web applications or marketing materials, it is worth noting that QR codes can also encode Base64 data. If you need to encode a small image or binary payload as a QR-readable string, our Base64 Encoder/Decoder prepares the data string in precisely the format needed — making the combination of these two tools a powerful micro-toolkit for any developer working with encoded, portable data.
