Getting Startet

You can use the QRtag.net API as a normal image. Just use the following URL structure:


Your QR code will link by default with the page on which is was embedded. If you want to use another URL add the "?url=[URL]" parameter, where [URL] is the URL that the QRtag links. For the image output you can choose between PNG (a transparent bitmap image) or SVG (a vector orientated image). The size of each pixel can be determined with the [size] parameter.
