Grid infrastructures proved to be useful in supporting processes that are intensively requiring computational resources. Several scenarios are identified when document conversions are requested and the response time is an issue. The results of two experiments are presented confirming that the usage of a Grid infrastructure is a convenient technical solution. References [1] D. Petcu, S. Panica, D. Banciu, V. Negru and A.
