Not exactly. You don't create energy from matter or matter from energy, you convert particles (through annihilation, pair creation, decay) into different particles, which "store" energy in different ways. Hadrons, like protons and neutrons, have enormous binding energy (energy that keeps their building blocks - quarks - together). In everyday life, that energy just quietly sits there and is responsible for almost all mass that we experience, but under specific circumstances, like meeting an antiparticle, those hadrons can be converted into other particles, like electrons and photons, which aren't composed of quarks, meaning all that enormous binding energy is converted into a "more obvious" form like kinetic energy or energy of electromagnetic radiation.
So, can you for example convert electromagnetic radiation into matter? Well, it already happened once, under the super-extreme conditions of the early universe. However, such process should create equal amounts of matter and antimatter (that's why it's called pair creation), which would annihilate back into radiation. For some unknown reason, which is one of the greatest unsolved problems in physics, there was a tiny bit more matter than antimatter, which is why stars, planets, humans and masturbatory escapism scribbles exist at all.
