Why Convert PNG to JPG?
PNG is ideal for screenshots and graphics, but overkill for photos. A 5 MB PNG photo becomes 500 KB as JPG with imperceptible quality difference. Many upload forms have file size limits that PNG photos exceed but JPG photos don't.

Quality Note
PNG to JPG is a lossless-to-lossy conversion. At quality 85%, the visual difference is negligible for photographs. File sizes typically drop 60-90%. Important: JPG doesn't support transparency — transparent areas become white.
