Make a code for a WiFi network, a link or any text — choose the colours, the size and how much damage it should survive, and put a logo in the middle. Or read a code out of a photo, a screenshot or your camera. Nothing is stored: the codes are built for the page you are on and the pictures you send are read and discarded.

This tool needs JavaScript: the code is drawn and the picture is read without the page reloading. Switch it on for this site, or reload if the connection dropped a file, and the controls appear.
