The games were ported by TOSE from the original Super Nintendo Entertainment System versions. Final Fantasy Anthology was published in North America on October 5, 1999 by Square Electronic Arts and in the PAL region on May 17, 2002 by Sony Computer Entertainment Europe.

In Japan, all three games were released for the PlayStation both individually and packaged together as part of a limited edition box set called Final Fantasy Collection. Although all three games differ little from the original Japanese versions in terms of gameplay, graphics, and sound, a number of extras were added, including art galleries, bestiaries, and two full motion video opening and ending sequences not present in the original releases.

As the North American release did not include the PlayStation port of Final Fantasy IV, that title was subsequently packaged with Chrono Trigger and released two years later as Final Fantasy Chronicles in 2001. The PlayStation port of Final Fantasy VI was released separately in Europe. Early versions of the PlayStation 2 console were incompatible with both the North American and European versions of Final Fantasy Anthology, although these incompatibilities have since been addressed in later hardware revisions. The "Fast" disc speed of the PlayStation driver in the PlayStation 2 can be used to decrease load times in Final Fantasy Anthology.
