Abstract: Systems and methods are described for generating dynamic web clippings. A web clipping service can obtain from a client computing device metadata for a dynamic web clipping, which includes an identifier of a web document and state information of a web browser that has rendered the web document on the client computing device, the state information enabling replication of a browsing session of the client computing device. The web clipping service can use the metadata to recreate the browsing session of the client device on the web clipping service, and capture an image of the web document as rendered within he recreated browsing session. The web clipping service can then provide the image of the web document as the dynamic web clipping.
