Infodumps cannot be done well.
To understand why, we need to understand the difference between an Infodump and presenting exactly the same information as "story".
An infodump is where we load the reader up with all sorts of information about the world, or the origin or childhood of a character, or the politics or religion or culture that is important to the motivations and decisions of the characters.
Basically, as a shortcut, we are just asking the reader to memorize all these facts, and readers are terrible at memorizing facts, and bored with memorizing facts.
The purpose of a fiction (book, movie, comic, even poetry, music or song lyrics) is to evoke imagery in the reader. To guide the audience in seeing, feeling, and experiencing the life of the characters. That is story. That is immersion. A vicarious "being there".
Even music without lyrics, like Ein Klein Nachtmusik by Mozart, can transport listeners. That is just fun and joyful, playful music, and it evokes that sentiment in the audience, time and again, bypassing language and culture barriers. Mozart found a joyful commonality in people and devised a musical way to bring it forth.
Just like really good comedy writers can find a ludicrous commonality that most people cannot help but laugh it.
The job of the author is to assist the audience in imagining and feeling what the author is imagining and feeling, or close enough. The sights, the attitudes, the fear or joy or despair or grief. It is bring forth these commonalities in sentiment.
Infodumps are trying to shortcut this process. It is basically saying "Here is a bunch of stuff you must memorize for my story to make any sense", without any attempt to actually make this interesting.
If there is any information actually crucial to the story, it needs to be presented in imaginary scenes with a central figure the audience is watching.
When Luke Skywalker first learns of the force, all the information he gets is presented in scenes, in conversations, and he is resistant to this. There is tension, some old man and crew he doesn't know, just after his caregivers have been murdered, he's been whisked away from his home and everything he knows.
There is emotional context now in delivering the information. How much worse would the movie be if all of that drama was just replaced by another expository scroll in space, explaining the Force, so that after these horrific losses, we can just cut to Luke practicing with the light saber like none of it happened?
Information must be presented in scenes, and it has to matter both to the plot (WTF happened? Why would my Aunt and Uncle be murdered? Why do I have to leave?) and to the central figure in this chapter (Luke).
Infodumps don't really work with readers. They are definitely shorter, but it is better to spend 250 words presenting a piece of information in a scene, than to spend 25 words presenting it as exposition to be memorized.
And I will remind you, that people that read for entertainment do not mind reading. You don't have to worry about adding a well-written 250 words, instead of 25 words. They aren't trying to get through your story fast.
Because readers remember the scenes they immersed themselves in, and they remember very little of the exposition they were supposed to just memorize and recall when needed.
Find a way to present plot critical information in scenes with emotional content. You have to invent those scenes. Perhaps they are scenes from your protagonist's childhood. Don't try to shortcut it, no matter how many words it takes, you have to present information embedded in scenes people can imagine.
