Why check a checksum?

Downloads get corrupted, and files sometimes come from somewhere other than the publisher. A matching value means not one character of the contents differs.

Why does it compare automatically?

A SHA-256 is 64 characters long. Comparing by eye makes it easy to miss a single different character in the middle.

Does the file go to a server?

No. It is read and hashed inside your browser only.
