Why Does PNG to JPG Look Worse?
PNG→JPG is a deliberate quality/compatibility trade. Photos tolerate it; logos and screenshots suffer more.
Problem: After PNG → JPG, edges halo or the background turns solid.
Solution: Raise JPG quality for photos; keep PNG/WebP for UI/transparency. Don’t loop JPG saves.
Lossy encode
JPEG discards detail — fine for photos, rough on text.
Transparency
Alpha becomes a flat background color. That isn’t a bug.
Better targets
Need smaller with alpha? Try WebP. Need perfect UI? Stay PNG.
Fix it in three steps
- Choose intent. Photo share → JPG. UI → stay PNG/WebP.
- Convert carefully. PNG → JPG at high quality when needed.
- Avoid loops. Don’t recompress the JPG repeatedly.

FAQ
Why does PNG to JPG look worse?
JPG is lossy and drops transparency, so UI and logos can look softer or flattened. Use higher quality for photos, or keep PNG/WebP for sharp graphics.
Can I get transparency in JPG?
No. Use PNG or WebP when you need alpha.
