Frequently asked questions
Do QR codes expire?
No. This generator encodes your content directly into the pattern — there is no redirect service in between, so it works forever.
What error-correction level is used?
Level M (~15% recovery), the sweet spot between robustness and density for printed codes.
Is there a tracking redirect?
No — the code is generated locally and contains exactly the text you typed. Nothing is shortened or tracked.
Will it scan from a screen?
Yes. For best results keep the default white margin (quiet zone) and avoid scaling the PNG down too far.
