AB We introduce a new family of generalized parton distribution models able to fulfill by construction all thetheoretical properties imposed by QCD. These models are built on standard parton distribution functionsand extended to off-forward kinematics through a well-defined procedure. We apply this strategy on thepion, first handling a simple but insightful algebraic model, and then exploiting state-of-the-artcomputations obtained in continuum QCD. We compare these models with a more standard one relyingon an xFitter extraction of the pion parton distribution functions. The results for both quark and gluongeneralized parton distributions are presented and exploited for calculation of electromagnetic, gravitational,and Compton form factors. Results on the latter highlight the relevance of next-to-leading-ordercorrections, even in the so-called valence region
