How to specify compression ratio when archiving tar?

Question

linux

Command:
tar -czvf file.tar.gz *.html
Creates an archive file with all html files in a folder. What is their default compression ratio? Can it be changed somehow?

Answer 1

SSH has nothing to do with it.
The compression ratio has the gzip you are using. Possible values ​​are from 1 to 9.
PS gzip is not the best option for getting maximum compression.
