What happens to transparency converting PNG to JPG?

JPG has no transparency, so transparent areas are filled with a background color (usually white) during conversion.

Does converting PNG to JPG reduce quality?

JPG is lossy, so there's some compression, but at high quality it's rarely visible — and the file gets much smaller.

JPG vs PNG: when to use each

The rule of thumb: JPG for photographs, PNG for graphics with sharp edges or transparency. Here's why, and how to convert either way.

Use JPG for photographs

JPG's lossy compression is tuned for continuous-tone images like photos, where it produces small files with little visible loss. Avoid it for text or sharp graphics — the compression creates blurry artifacts around hard edges.

Use PNG for graphics and transparency

PNG keeps every pixel exact, so logos, icons, screenshots and anything with crisp edges or a transparent background stay clean. The trade-off is larger files for photographic content.
