Why convert JPG to PNG?
PNG uses lossless compression, so the image never degrades when re-saved. It also supports a full alpha channel (transparency), which JPG does not - making it the right choice when you need to place an image on a non-white background. .PNG also handles text, screenshots, and graphics with hard edges better than JPG, keeping them crisp across multiple edits.
