'Anpassen' (to adapt / adjust) is a separable verb made up of 'an' (to/at) and 'passen' (to fit). The base verb 'passen' means 'to have the right size' or 'to be suitable'. The prefix 'an' expresses adjustment or alignment. So 'anpassen' means to make something suitable for something else.
Der Techniker passt die Einstellungen an die Wünsche des Kunden an.
The technician adjusts the settings to the customer's wishes.
The prefix 'an' is separable and goes at the end in a main clause. In a subordinate clause, the whole verb goes at the end, and in the infinitive with 'zu', 'zu' goes between 'an' and 'passen'.
Ich passe meine Pläne dem Wetter an.
I adjust my plans to the weather.
It is important to distinguish between the reflexive and transitive uses. 'Sich anpassen' (to adapt) means that a person changes their own behavior. 'Etwas anpassen' (to adjust something) means that you change an object or thing.

The children adapted quickly to the new school.
The target of the adjustment is expressed with the preposition 'an' and the accusative. This applies to both the reflexive and the transitive use.

You have to adjust your speed to the traffic conditions.

Ändern generally means making something different. Anpassen means making a change specifically in line with certain requirements, needs, or circumstances. With a text, anpassen is therefore especially appropriate when a specific target audience is the standard used to guide the changes.
