A network system may include a conversion server device and a computing system disposed within a remote network management platform. The computing system may be configured to: receive, from a client device of a managed network, a view request for a file that is associated with a file identifier and stored in the computing system; in response to receiving the view request, determine that the file is in a first format; based on the determining that the file is in the first format, transmit, to the conversion server device, a conversion request so that the conversion server device then converts the file from the first format into a second format that is based on a rasterized representation of the file; receive the file in the second format from the conversion server device; and transmit the file in the second format to the client device.
