Veneziano was born in Venice, where he trained as an artist, though his teacher is unknown. He initially copied prints by Albrecht Dürer and Giulio Campagnola from about 1512-14, and then producing his own works, somewhat in the style of the latter. He spent some time in Florence around 1515-16. He moved to Rome, perhaps as early as 1514, and by 1516 had joined the printmaking workshop of Marcantonio Raimondi, of which he was one of the most important members until it was broken up by the Sack of Rome in 1527. Unlike many produced by the workshop, most of Agostino's plates avoided being confiscated and melted down by Charles V's soldiers, and continued to be printed in later years. Agostino returned to Venice after the sack, and later visited Mantua and Florence before returning to Rome in 1531, remaining until at least 1536. It is assumed he died there, though there is no documentation.
