Quality vs. file size
Most photos can be compressed a lot before the difference is visible, because the eye doesn't notice small changes in detailed areas. Start around 70–80% quality and only go lower if you need an even smaller file.
For graphics with flat colours or text, keep the quality higher to avoid blurry edges.
