Qr-Cow - Dynamic QR Code Generator 作成者: Qr Cow

Any page. One click. A styled QR code.

Click the toolbar button and the current tab's URL is already a QR code. Right-click any link or selected text to encode that instead. Download PNG or SVG, or copy the image straight to the clipboard.

Private by design. Codes are generated entirely inside your browser: the extension makes zero network requests, collects nothing, and needs no account. What you encode never leaves your machine.

13 content types: URL, plain text, Wi-Fi login, vCard and MeCard contacts, email, SMS, phone call, calendar event, location, social profile, crypto address, and app link.

16 designer presets, the same styles as qr-cow.com (gradients, rounded dots, custom colors), rendered with the same engine, so the output is pixel-identical to the full studio. A live contrast check warns you before you ship a code phones can't scan.

10 languages, including full right-to-left layouts for Farsi and Arabic.

Need editable-after-printing (dynamic) codes with scan analytics? That lives in the full studio at qr-cow.com: free static codes forever, dynamic from $3/month.
