How compression works
Lossy compression removes visual information that the human eye cannot easily detect — subtle colour variations and high-frequency detail. At 80% quality, most people see no difference from the original, but the file can be 60% smaller.
Quality vs file size
| Quality | Typical size reduction | Recommended for |
|---|---|---|
| 100% | 0–10% | Archival, print originals |
| 90% | 30–50% | Photography portfolios |
| 80% | 50–70% | Most web photos — sweet spot |
| 60% | 70–85% | Thumbnails, previews |
| 40% | 85–95% | Low-priority backgrounds only |
