Static vs dynamic QR codes (plain English)
Static vs dynamic QR codes explained. When free static is safer for print, and when paid dynamic is worth it.
Our Promise
Static codes on QR Promise are generated in your browser, contain your data directly, and never route through us — so they can never be deactivated.
Static
Data lives in the pattern. Pros: works offline forever, no subscription. Cons: cannot change destination without reprinting; no built-in scan stats.
Dynamic
Pattern points at a short URL you control. Pros: edit destination, analytics. Cons: depends on a host; unpaid trials can die.
Rule of thumb
Print that must last years → static. Campaign you will tweak weekly → dynamic on a plan you keep.
QR Promise
Free = static. Pro ($3/mo) = dynamic + analytics + migration help.
