Verdict: JPG wins for photographs — far smaller files at visually identical quality. PNG wins whenever you need transparency, crisp text, or pixel-perfect graphics. Rule of thumb: photos go JPG; logos, screenshots, and anything transparent goes PNG.
| Criterion | PNG | JPG |
|---|---|---|
| Compression | Lossless — large files for photos | Lossy — tiny files for photos |
| Transparency | Yes, full alpha channel | No transparency support |
| Text and line art | Crisp edges, no artifacts | Smudges and ringing around sharp edges |
| Photographs | Wasteful — often 5–10x larger than JPG | Ideal — small with excellent visual quality |
| Re-saving | Lossless, re-save freely | Each re-save at low quality degrades detail |
| Best for | Logos, UI, screenshots, transparency | Photos, thumbnails, camera images |

No — conversion cannot restore detail that lossy compression removed. It only makes the file bigger. Convert PNG to JPG to save space, not the reverse for quality.
Quality 85–92 is the sweet spot for photos: visually near-identical to maximum with a fraction of the file size. Below ~70, banding and block artifacts become visible.
PNG stores every pixel losslessly, so detailed screenshots balloon. For sharing, convert to JPG (or WebP) — text stays readable at high quality settings.
