Lower quality means a smaller file. 92% is close to visually lossless; below about 60% you start to see blocking around edges and text. Only JPG and WebP have a quality setting.
JPG and BMP cannot store transparency, so anything see-through has to be filled in. White suits documents, scans and product shots; black suits screenshots of dark interfaces and logos drawn in light ink.
