PNG is lossless, so quality does nothing here.
Editing is the reason to choose PNG here. A HEIC has already thrown away detail to be small, and every JPG saved on top of it throws away a little more. PNG records each pixel exactly and never degrades, so a picture headed for a design tool, a report, or a mock up begins from the best copy that remains, and survives being saved twenty times on the way.
Size, and a great deal of it. Recording pixels rather than approximating them means a photograph that sat in two megabytes as a HEIC can want twenty as a PNG. That is nothing on a desktop and genuinely painful over mobile data or as a mail attachment.
Do not choose PNG to send a picture to a person. Sharing is the one job it is bad at, and plenty of upload boxes refuse it on size alone. Convert to JPG for that. PNG repays its bulk only when the picture is about to be worked on.
