Images were converted to a lower-bit format, code was minified, and the entire page was repackaged into a lightweight binary format called OBML (Opera Binary Markup Language). The phone’s client, that tiny 1.21 MB program, was simply a highly optimized rendering engine for this compressed data. This meant the browser itself could be minuscule because the heavy lifting was done in the cloud.
