Qr Code as a Service

QR Code for this page

Welcome to my QR Code generator service. It only do 1 thing: display the QR Code for current page.

How to use

<img src="https://{localhost:3000}/v1" />

Just put the above code to your page and it will be replaced by a QR code referencing current page

How it works: When an image is embedded in a page the browser sends a request with the current page as a referer header. The service use that header to build and return the qr code as a PNG imnage.

Addtional parameters and customization

You can change the look of the qr code with the following parameters:

Colors

<img src="https://{localhost:3000}/v1?color=CC0000&amp;background=00000000" />

color and background (default value #000 and #FFF): allows to change the color respectively of the squares and background color. It should be an RGB code with hex values (ex: red as FF0000). It's even possible to use transparency in the code at the end of the code (ex: transparent is 00000000).

Example red on transparent:

<img src="https://{localhost:3000}/v1?size=200" />

size (default value: auto) : allows to enlarge the code to a define size. The image will be set to the specified size unless it's larger.
