Miniaturization

Miniaturization is when a fairy (Enchantix level) has to release all the negative force from her which will allow her to Miniaturize. The Winx first miniaturized in Season 3 Episode 22 (Crystal Labyrinth) so they can enter the crystal maze. Bloom couldn't because as she is an incomplete Enchantix fairy, although in Season 4, she can now because she became a complete Enchantix fairy. In Season 4, it is also revealed that Believix fairies can miniaturize too. Guardian fairies can miniaturize if they have no dark side in their souls

Season 3
When the Winx begin their third year at Alfea, they are told about their final Enchantix transformation as well as its additional powers it gives to fairies such as the use of Fairy Dust and the ability to Miniaturize themselves. Once the Winx gain their Enchantix, they are able to use their Miniaturization power except Bloom, whose Enchantix was incomplete since she gained it out of her will, not by saving someone. The Winx, minus Bloom, used this power numerous times throughout the season, such as in Episode 22, to enter the Golden Kingdom, and in Episode 26 (A New Beginning ) to escape when all the water of Lake Roccaluce was returning back to its place after Bloom temporarily defeated Valtor.



The Secret of The Lost Kingdom
The Winx Club were forced to use their miniaturization powers to gain access to the Tree of Portals so they could find a way of entering the realm of Obsidian. Only Bloom was incapable of entering because of her willed-on and therefore incomplete Enchantix.

Season 4
The Winx used it two times. Firstly, when they used it in the second episode (The Tree of Life) to be small enough to enter Pixie Village, which was Bloom's first use. In the eighth episode (The White Circle), they used it to get away from the Wizards of the Black Circle, and to help Roxy who was about to be attacked by the Wizards. This use was different than the others, because the girls were Believix fairies.
