Dynamic QR codes: print once, change the destination anytime

A dynamic QR code separates the printed code from the destination it opens. The code encodes a permanent short link — and you decide, today or in a year, where that link goes. Print it once, update it forever.

Static vs dynamic: the real difference

A static QR code encodes your final URL directly. It works forever with no service in between, but it is frozen: if the page moves, the printed code is waste paper.

A dynamic QR code encodes a short link (like l-k.us/menu42). The redirect happens when the code is scanned, so changing the link's destination instantly changes where every printed copy of the code leads — without touching the print.

Who needs dynamic QR codes?

• Restaurants and bars: one QR on every table, menu updated whenever prices or dishes change.
• Shops: window QR pointing to the current promotion, updated every week.
• Events: posters printed months ahead, programme page finalised the day before.
• Products and packaging: manuals, warranty pages and campaign pages that evolve after production.
• Real estate: one sign per property, relinked to each new listing.
• Business cards: your card outlives your current role — point it at whatever you do now.

Bonus: you also get scan statistics

Because a dynamic QR routes through a short link, every scan is counted. On Link Us you see scans per day, referrers and device types for each link — privacy-friendly, with no IP addresses stored. That tells you which poster location, table or flyer batch actually performs.

How to create a free dynamic QR code

• Create a free account on l-k.us (email verification takes a minute).
• Enable the two optional marketing consents in your account — they are what keeps dynamic features free.
• Create a new link with "Dynamic" checked, then press "QR" and download PNG or SVG.
• Print it. Whenever you need, edit the link's destination from your dashboard — every printed code updates instantly.

Frequently asked

Does a dynamic QR expire? No — Link Us links have no expiry date.

Does scanning get slower? No — redirects are served from an in-memory cache in milliseconds.

Can I convert a printed static QR to dynamic? No: what is encoded in a printed code cannot change. That is exactly why it is worth choosing dynamic before going to print.
