what is the difference between Object and Object ACL in AWS S3?

Question

I added a file into AWS S3 bucket. The access of the bucket is set to public. In the permissions, I set object and object ACL to read for everyone.

But I am not clear about the difference between Object and Object ACL, could you please explain their differences?

Thanks

Answer 1

Object refers to permissions to access the object (file) itself, such as downloading the object.

Object ACL refers to permissions to access/change the Access Control List of the object. That is, the permissions associated with the object.
