Welcome to the website of JSQR, the JavaScript QR Code Encoder Library!

JSQR is the first and only JavaScript Library that is able to encode different data formats, like vCards, vCalendar Events, geo coordinates etc. into QR codes directly in the browser on the client, without any requests to a remote server. This increases the flexibility, speed and security of web applications.

Try it yourself using the QR Code Generator or the Bookmarklet.
