In this contribution we discuss off-shell gluon amplitudes from worldline formalism perspective. We use the Bern-Kosower master formula and two IBP methods to extract the form factor of the off-shell three-and four-gluon vertices. For the four-gluon case we also discus its representation in N = 4 = 4 SYM.
