The short answer
Por acaso can mean ‘by any chance’ in a question and can also describe something that happened by chance. In everyday conversation, the question use is a handy way to ask about a possibility without assuming the answer.
Use por acaso to say ‘by any chance’
Its exact tone depends on the sentence and intonation. A calm question may sound like a polite check; a strongly stressed or repeated question can sound surprised or doubtful. Pay attention to how the speaker says it, not only to the dictionary translation.
Você conhece a Ana por acaso?
Do you happen to know Ana?
Você viu meu carregador por acaso?
Have you seen my charger, by any chance?
Encontrei esse livro por acaso.
I found this book by chance.
Separate a neutral check from a skeptical question
When you need something, use por acaso with a clear request and a friendly tone. When the phrase is part of a challenge—such as asking whether somebody did something they were not expected to do—it may sound skeptical. The surrounding conversation makes that difference clearer.
Por acaso is not the only way to ask politely. Você sabe…? (do you know…?) or você poderia…? (could you…?) may be more direct when you want a specific answer or action.

Você passou aqui ontem por acaso?
