A method and apparatus for transcoding content or elements of a webpage received at a client device, for example, a mobile communication device or other type of networked device. The apparatus includes a transcoding engine which is configured to transcode webpage content during a secure end-to-end connection between a client device and a website without the use of a proxy. According to an embodiment, the transcoding engine resides on the client, and is implemented as a plug-in to the browser, and transcoding instructions are provided to the client device by way of the signature file(s) each time the plug-in is invoked. The client device uses the transcoding instructions to manipulate the secure response from the secure server, for example, to transcode the response to a format suitable for display on the client device.
