Why is my JPG so much smaller than the PNG?

JPG uses lossy compression tuned for photographic content, while PNG stores every pixel exactly. For photos the JPG is often a fraction of the size with no visible difference.

What happens to transparent areas?

JPG has no transparency, so any transparent pixels are filled with a white background. If you need to keep transparency, convert to WEBP instead.

Are my files uploaded to a server?

No. The whole conversion runs in your browser using your device's own processor. Your files are never sent anywhere.

PNG keeps every pixel lossless, which makes photos and screenshots far bigger than they need to be. Converting to JPG shrinks the file dramatically for email, web pages and uploads — and it happens here in your browser, so nothing is sent to a server.
