PNG is a lossless format with transparency support. Some programs and workflows require PNG - for graphics with sharp edges or as an intermediate format while editing.
Note: PNG cannot recover detail JPG already discarded, but it avoids further quality loss. The conversion happens locally in your browser.
A typical use case is further editing: anyone who saves a JPG repeatedly accumulates fresh compression artefacts with every round. Convert it to PNG once and the pixels freeze, staying stable across every later editing step. PNG also works as a source for logos, icons and anything that needs sharp edges or a transparent background - properties JPG cannot offer by design.

Limitations: PNG is much larger than JPG for photos and will not make an already compressed JPG sharper again. Embedded metadata such as capture date, camera and GPS location does not survive the re-encode - only the image orientation is baked into the pixels beforehand.
No. Lost JPG detail does not return; PNG only prevents further loss.
For anything with transparency or sharp edges: logos, icons, screenshots with text and line drawings stay crisp in PNG, whereas JPG creates visible halos there. PNG is also the safe choice as an intermediate format across repeated edits. For pure photos, PNG rarely pays off.
No, everything stays local in the browser.
For photos usually noticeably so, often three to five times, because PNG stores losslessly without discarding detail. If you only need to view rather than edit, the JPG stays the more space-saving choice.
