An information processing apparatus communicating with an image forming apparatus includes a memory that stores a program and a processor that executes the program stored in the memory to perform a process. The process includes receiving a first document file including multiple sets of encrypted page data of pages, arranging the sets of the encrypted page data in page order, attaching identification information for identifying a page data boundary to each of the arranged sets of the encrypted page data, obtaining decoding information for decoding the sets of the encrypted page data from the first document file, generating a second document file including the arranged sets of the encrypted page data and the decoding information disposed before the arranged sets of the encrypted page data, and transmitting the generated second document file to the image forming apparatus.
