Printing a QR code normally commits you to one address. Linkfold turns that around: the code only holds a short, permanent address that the server resolves on every scan. Whether a scan shows a mobile link page or redirects straight away, and which links are on that page, can change at any time — the printed code stays the same. Design happens in the browser: colours for dots, corners and background, six dot styles, a logo in the middle. With a logo or round dots, error correction switches to the highest level by itself, and a warning flags low contrast. Export as a 2048-pixel PNG or as SVG for print. Changes save automatically about a second after the last edit; a counter shows scans per day and clicks per link. Instead of an account there is a private edit link. The interface is in English; it was built as a work sample for a job posting.
