An electronic file decomposition system is illustrated. A parser of the electronic file decomposition system decomposes an electronic file into different components based at least in part on metadata of the components. An interface of the electronic file decomposition system presents an interactive representation of the decomposed electronic file to a user. The user employs the interface to select components to retain and/or components to remove. A re-formater of the electronic file decomposition system generates a new electronic file based on the received electronic file and the user selections.
