FAQ
How much data can a QR code hold?
It depends on the error-correction level and character type: pure digits hold up to ~7000 characters, while ordinary text should stay under ~2000 characters. Longer content makes the code denser — consider using a short link.
Is my content uploaded to a server?
No. QR codes are generated by local JavaScript, so whatever you type never leaves your browser.
Which QR standard is used?
This tool produces standard QR Code (ISO/IEC 18004), compatible with WeChat, Alipay, camera apps and every major scanner.
