Quick answer
Use into for movement or transformation (walked into the room, turned into a frog). Use in to when “in” attaches to the verb and “to” starts a new phrase (turned the report in to my manager).
Into is a single preposition of motion. “In to” is a coincidence, two words that happen to land next to each other because the sentence structure puts them there. Telling them apart is a matter of asking which word each one belongs to.
Quick Answer
If the sentence describes entering, inserting or becoming, use into. If “in” completes a phrasal verb (turn in, drop in, log in, give in) and “to” introduces what follows, keep them separate.
Into (movement)
She walked into the meeting late.
Into (transformation)
The sketch turned into a full painting.
In to (phrasal verb)
I turned my notice in to HR.
In to (phrasal verb)
He logged in to check the results.
Contrast
“She logged into the system” is widely accepted; “she gave in to the pressure” never becomes one word.

Common Mistakes
- “I dropped into say hello” should be “dropped in to say hello.”
- “Look into it” is correct, into here means investigate.
- Using “in to” for plain movement: “ran in to the room” means something different from “ran into the room.”
