PNG uses lossless compression — no further quality degradation when editing and re-saving. Every time you edit and save a JPG, it loses quality. Converting to PNG stops this degradation cycle.
PNG supports alpha transparency while JPG doesn't. Convert to PNG when you need to add transparent backgrounds in image editors — essential for logos, overlays, and design compositing.
PNG handles text, line art, screenshots, and UI elements perfectly. JPG compression creates visible artifacts around high-contrast edges. If you're working with images containing text or sharp graphics, PNG preserves them cleanly.
JPG is better when file size matters more than perfect quality — photos for web, email, and social media. PNG files are 3-5x larger than JPG for photographic content.
No — it can't restore quality already lost in JPG compression. The benefit is preventing further quality loss from re-saving and gaining transparency support.
