Export for the actual display density: an image shown at 600 CSS pixels may need a 1200-pixel source on a 2× screen, but a 4000-pixel file still wastes bandwidth. Compare candidates at their final dimensions and inspect text, faces, gradients and saturated edges; chroma subsampling can damage colored text before general blur becomes obvious. Keep one untouched master, resize once, and encode each derivative directly from it. Repeated JPEG conversions accumulate artifacts even when every individual quality setting looks moderate.
