About QR Code Generator
A QR code generator turns a piece of text — most often a URL, but also plain text, contact details, or Wi-Fi credentials — into a scannable two-dimensional barcode. Anyone with a smartphone camera can point at the code and instantly open the link or read the content, which is why QR codes appear on posters, business cards, product packaging, restaurant menus, and event tickets.
This generator runs entirely in your browser using a well-tested QR encoding library. Because nothing is uploaded, the data you encode stays completely private — important when you are generating codes for internal URLs, private events, or anything you would not want logged by a third-party service.
Choosing a size and error-correction level
Larger sizes are easier to scan from a distance and print more crisply, while smaller sizes fit neatly into tight layouts. The error-correction level controls how much of the code can be damaged or obscured while remaining scannable: higher levels add redundancy so the code still works even if part of it is covered — useful when you place a logo in the center or print on a surface that may smudge. Medium is a sensible default for most uses.
Common uses
Businesses link QR codes to menus, payment pages, and app downloads. Event organizers encode ticket confirmations and venue maps. Individuals share contact cards, Wi-Fi passwords for guests, and links to their portfolios or social profiles. Because the output is a standard image, you can drop it into a document, slide deck, or printed design.
