qr.tl (pronounced 'qwertle') is a real time image manipulation service that lets you crop, compose, scale, tint, slice and dice images as well as generating QR codes without having to have any software installed on your webserver or PC.
If you have found your way to this site, its probably due to word of mouth. We are in stealth mode at the moment so shhh :)
There will be a website here soon to help you create qr.tl templates. For now instructions and a description of the how the service operates can be found here.
