Download
Save a single PNG, or all of them in one ZIP.
A JPG's compression already happened when it was saved, and PNG can't bring back detail that was dropped. The PNG shows exactly the same picture.
What PNG gives you is a lossless file: you can edit and save it as often as you like without it compressing again, and many design apps and some upload forms ask for it.
Expect the PNG to be several times larger than the JPG, because it stores every pixel exactly. If you only need a smaller file, convert the other way.
PNG can hold transparency, but converting doesn't make anything transparent: the photo's background is still there. Remove it in an editor after converting.
macOS comes with sips, which converts from Terminal:
- sips -s format png photo.jpg --out photo.png

Questions
No. Each JPG is decoded and written as PNG in your browser. Nothing is sent anywhere.
No. The PNG shows the same pixels as the JPG. It just won't lose any more when you edit and save it again.
PNG compresses without loss, and photos have too much fine detail for that to make them small.
No. Phones often store a photo sideways with a note to turn it; the PNG is saved the way the photo is shown.
No. Converting keeps the background. Remove it in an editor afterwards; the PNG can then hold the transparency.
Yes. Drop them together, and the download button saves every PNG in one ZIP.
