TransparencyConverting a JPG does not remove its background
File sizePNG may be larger than the original JPG
Image quality
The original JPG compression artifacts remain. Changing format does not restore lost detail.
Transparent backgrounds
PNG supports transparency, but this conversion does not separate a subject from its background.
Larger output files
PNG uses a different compression method. A larger file is not automatically an error or evidence of better quality.
Editing and upload requirements
Use PNG when the destination specifically requires it. Keep JPG for compact photographic delivery when PNG is unnecessary.
