Are my images uploaded to a server?

No. All conversion happens locally in your browser.

Will the PNG be larger than the original JPG?

Yes. PNG is lossless so files are typically larger than JPG.

No. JPG already discards some detail, so converting to PNG preserves the current quality but cannot restore lost data.
