Will compression affect image resolution?

No. Compression only reduces file size by adjusting quality parameters. The image width and height resolution remain unchanged.

What compression level is recommended?

A quality setting of 70-85% is virtually indistinguishable to the eye while reducing file size by 50-70%. Adjust based on your needs.
