Our purpose
NightNote QR is an independent, free QR tool website operated at qr.nightnote.cn. We make common QR tasks direct and understandable: open a page, enter content, inspect the live preview, and download. There is no account, paywall, or watermark.
Why local generation matters
Text, WiFi credentials, business cards, email addresses, phone numbers, and messages can all contain information you do not want to hand to a third party. We therefore use the open-source qrcode-generator library to encode content in your browser. Your QR input is not uploaded to our server or saved as account data. Infrastructure providers such as Cloudflare may still process technical logs needed to deliver the site; any future advertising processing is covered in the Privacy Policy.
What we provide
The site covers general text, URL, WiFi, vCard, email, phone, SMS, and WhatsApp codes. Each tool offers size, foreground, background, error correction, and margin controls, plus PNG and SVG export. Guides below the tools explain format differences, appropriate uses, and print testing so that a code is not merely generated but reliably scannable.
Editorial and operating approach
Our explanations are written for these tools and are not official documentation for third-party products. WhatsApp, Google, Cloudflare, and other names belong to their respective owners; no affiliation or endorsement is implied. Reserved advertising placements are intended to support maintenance. Ads never appear above or inside the tool. We do not sell user input because that input is not transmitted to us in the first place.
Feedback and improvement
Compatibility varies across phones, camera apps, and print conditions. To report a reproducible format error, accessibility issue, or broken page, use the Contact page and include the device, browser, URL, and steps. Never include a real WiFi password or another secret in a support email.
