Converting JPG to PNG produces a losslessly-compressed copy of the pixel data. The file will typically be 2–5× larger — because PNG stores every pixel faithfully, while JPG already discarded fine detail at save time. The conversion doesn't restore anything JPG removed; what you gain is a container that won't degrade further on repeated edits and re-saves, and that natively supports full transparency if you add it later in an editor.

Common questions for JPG→PNG
Does converting JPG to PNG improve quality?
No. JPG compression discards pixel data permanently. Converting to PNG preserves exactly what the JPG contains — no better, no worse. The quality ceiling is whatever the original JPG had.
Why is my PNG larger than my JPG?
PNG uses lossless compression — every pixel is stored faithfully. JPG achieves small file sizes by permanently discarding fine detail. A larger PNG is normal and expected.
Does PNG support transparency if my JPG didn't have any?
The PNG format supports an alpha channel, but your converted file won't have transparency unless you add it afterward in an editor. JPG has no transparency data to carry over.
When should I convert JPG to PNG?
When you need to edit and re-save repeatedly without further quality loss, when you need transparency support going forward, or when you're providing a source file for print or design work.
