Reception
According to review aggregator Metacritic, Opera Omnia received "mixed to average" reviews.

Nick Tylwalk of TouchArcade praised the game for not being a "gacha grab" and "generous" with its currency, lauding it as a good example of appropriate fan service.

Christian Colli of Multiplayer.it rated it 8/10 points, praising the combat system as fun and original, but criticizing the game's repetitiveness and lack of an Italian localization.

Harry Slater of Pocket Gamer called Opera Omnia "fairly standard" and said it would be more appealing to dedicated fans of the series.

On June 2022, Dissidia Final Fantasy Opera Omnia announced it had surpassed 10 million downloads.

Preservation attempts
A user named "Hatok", in an act of preservation, recorded all the cutscenes and battle sequences from the game's story line. The upload included the canon weapons of each character, and made sure that the battle sequences included the canon characters. The project was run, maintained and supported by Hatok himself, and was finished 7 hours before the shutdown of the system. The project is about 100 hours long, and took up more than 2 terabytes of video storage.
