자주 묻는 질문
Does the QR code expire?
No. This QR code generator creates static QR codes: your content is encoded directly into the pattern itself, so there is nothing to expire. Codes that stop working come from dynamic QR services that route through a short link. A code made here keeps working forever, even in print.
Is my URL or text uploaded to a server?
No. QR code generation runs 100% in your browser — neither your input nor the generated image is ever transmitted. Only your settings (size and error correction level) are kept in this browser's localStorage; the text itself is never stored.
My QR code won't scan — what should I check?
Check in order: ① the white margin (quiet zone) around the code hasn't been cropped, ② the printed size is large enough (roughly 1/10 of the scanning distance), ③ there is strong contrast with the background, ④ for long content, raise the error correction level or shorten the URL. This free QR code generator always outputs the required 4-module quiet zone.
What is the difference between error correction levels L, M, Q and H?
It is how much of the code can be damaged and still scan: L ≈ 7%, M ≈ 15%, Q ≈ 25%, H ≈ 30%. Higher levels make the pattern denser and reduce the maximum text length. M suits most uses; pick H if a logo will overlap the code or it may get dirty.
Can I use the QR codes commercially?
Yes. QR codes you generate and download as PNG are yours to use freely — business cards, menus, posters, packaging, slides and any other commercial use — with no watermark, no fees and no restrictions.
