MORE ABOUT "공짜"
공짜 means the same as '무료'
공짜 actually sounds quite casual and you will not use the word for official situations such as documents or business meetings. For such situations, try to use 무료 instead.
For example, in the hotel, you might find this sign that says 'Wifi 무료'
When you ask someone to see if something is free, you can say '이 XX는 무료입니까?'
For example, 이 주스는 무료입니까? 이 사과는 무료입니까? 이 책은 무료입니까?
The opposite word is '유료 (paid)'. You may find the signage in front of buildings in Korea that says '유료 주차장' which means "paid parking"
