常见问题
Are these static or dynamic QR codes?
They are static: the content is encoded directly into the QR code and never changes. There is no redirect, no tracking and no account — which also means no scan analytics and no editing after printing. If you need to change the destination later, you'd need a dynamic QR service (not offered here, by design, for privacy).
Is my content or logo uploaded?
No. The QR code and any logo are generated entirely in your browser. Nothing is sent to a server, stored or logged.
Which formats can I export?
PNG (raster, with transparent background support) and SVG (clean, scalable vector). Choose any export size; SVG stays sharp at any scale.
Will a logo or heavy styling break scanning?
It can. Adding a logo automatically raises error correction to High, and the tool warns you about low contrast, an oversized logo or too little quiet zone. Keep good contrast (dark on light) and a margin for reliable scans.
Is there a limit or watermark?
No. It is completely free, with no signup, no subscription, no watermark and no hidden limits.
