Quality slider: what each band actually buys you
| Quality | Typical size reduction | Visible artefacts | Recommended for |
|---|---|---|---|
| 90–95% | Small — sometimes under 20% | None | Photos you will print or show full-screen |
| 75–85% | Often 50–70% | Only under close inspection | The web, email and social uploads — the usual sweet spot |
| 50–70% | 70–85% | Blockiness in smooth gradients like skies | Thumbnails and previews |
| Below 50% | Very small files | Clearly visible ringing and banding | Placeholders and internal drafts |
