Noticeably smaller for photos. Heads up: JPG has no transparency, the alpha channel becomes a white background.
- Your file never leaves your device — the server never receives or sees it.
- JPG is usually a fraction of the size of PNG, especially for photos rather than flat graphics.
- JPG doesn't support transparency: transparent areas turn white — that's expected, not a bug.
