ないでください is a polite way to ask someone not to do something. It's neutral and can be used with strangers or people of equal status. In contrast, お〜ください is an honorific request form used with superiors, customers, or others of higher status.

The ないでください form is used to make polite negative requests, similar to the English 'Please don't do [this.]' In comparison, the dictionary/non-past form of a verb + な expresses an extremely blunt or brusque command not to do something. The two forms have similar meanings (telling someone not to do something) but vary greatly in politeness level.

ないでください is a polite way to ask someone not to do something. The shorter form, ないで, is more casual and typically used with close friends or family. While ないでください is appropriate for strangers or people of equal status, ないで has a softer, more informal tone. Adding the sentence-ending particle ね (e.g. 食べないでね) makes the request even gentler and more caring.

Both Verb[ないで] and ないでください are used to express requests not to do something. While ないでください is polite, and can be used with strangers or people equal in status to you, Verb[ないで] (without ください) is more casual, and typically used to make requests of friends or family members in a casual tone. Requests with てください and especially Verb [て] can be followed by ね (e.g. 食べてね) for a softer, more gentle feeling.
