We develop a unified algebraic model which satisfactorily describes the internal structure of pion and
kaon as well as heavy quarkonia (ηc and ηb). For each of these mesons, we compute their generalized parton
distributions (GPDs), built through the overlap representation of their light front wave function, tightly
constrained by the modern and precise knowledge of their quark distribution amplitudes. From this threedimensional
knowledge of mesons, we deduce parton distribution functions (PDFs) as well as electromagnetic
form factors and construct the impact parameter space GPDs. The PDFs for mesons formed with
light quarks are then evolved from the hadronic scale of around 0.3 to 5.2 GeV, probed in experiments. We
make explicit comparisons with experimental results available and with earlier theoretical predictions.
