Does PNG to JPG Lose Quality?
PNG is lossless (and can carry alpha). JPEG is lossy and flat. Converting is common for web photos and email, but it is a one-way door for discarded detail and for alpha channels.
Verdict: PNG → JPG can reduce quality and always drops transparency. Use high quality for photos; keep PNG/WebP lossless for UI, logos, and screenshots with text.
Photos
A high-quality JPG export of a photographic PNG is often visually fine and much smaller. Artifacts show up at low quality or on flat gradients.
Screenshots and UI
JPEG smears text and icon edges. Prefer PNG or lossless WebP.
Transparency
JPG has no alpha. Transparent PNGs get a matte background on convert.
Key points
- JPG is lossy — some detail can vanish.
- Alpha does not survive JPG.
- Raise quality for photo delivery; avoid JPG for crisp UI.
